Same issue with 4.8.6-201 Same issue with 4.8.8-300 on F25 Same issue with 4.8.10-300.f25 Please provide the full dmesg output from a fresh boot. Does this problem happen if you don't have your 3rd party modules loaded? Created attachment 1227535 [details]
Full fresh boot kernel log
I'm not sure what you mean re "3rd party modules loaded". I'm using stock Fedora kernel, no custom or out-of-tree modules. (In reply to Arcadiy Ivanov from comment #6) > I'm not sure what you mean re "3rd party modules loaded". I'm using stock > Fedora kernel, no custom or out-of-tree modules. CPU: 2 PID: 1061 Comm: NetworkManager Tainted: G OE 4.8.4-200.fc24.x86_64 #1 The O taint means you had something loaded that is not part of Fedora's kernel build. That doesn't appear to be present in your latest dmesg attachment. That would be an nvidia bumblebee driver but it loads late and not at all in the recent 4.8 kernel versions without there being pcie_port_pm=off. Whether it's loaded or not has no effect on iwlwifi. A bit more info on behavior - on some boots the iwlwifi never recovers requiring another reboot, and sometimes it takes just one hardware restart for the problem to resolve itself (like in a dmesg above). Same issue on 4.8.14-300.fc25.x86_64. Same with most recent BIOS. Hardware name: Dell Inc. Precision 7510/0M91XC, BIOS 1.9.4 11/04/2016 Hello, Same problem on a clean Installation of F25 (and even after update) on Lenovo P50. - 4.8.14-300.fc25.x86_64 04:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a) Subsystem: Intel Corporation Device 0130 Flags: bus master, fast devsel, latency 0, IRQ 134 Memory at d4c00000 (64-bit, non-prefetchable) [size=8K] Capabilities: [c8] Power Management version 3 Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [40] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [140] Device Serial Number e4-a4-71-ff-ff-9f-61-f4 Capabilities: [14c] Latency Tolerance Reporting Capabilities: [154] L1 PM Substates Kernel driver in use: iwlwifi Kernel modules: iwlwifi I also compared the hash for /usr/lib/firmware/iwlwifi-8000C-13.ucode to the file from Intel site https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-8000-ucode-25.30.13.0.tgz to the one in the iwl7260-firmware.noarch package -- same hash.

journalctl -b0 ## after restart
Apparently the same issue on 4.8.15-300.fc25.x86_64 on Lenovo P70 I attach full dmesg log from a fresh boot and lspci -vv following this message. The first Microcode error appears at [ 21.745213] iwlwifi 0000:04:00.0: Microcode SW error detected. Restarting 0x82000000. and repeats: [ 21.992697] iwlwifi 0000:04:00.0: Microcode SW error detected. Restarting 0x82000000. [ 22.202975] iwlwifi 0000:04:00.0: Microcode SW error detected.

*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 25 kernel bugs. Fedora 25 has now been rebased to 4.9.3-200.fc25. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 26, and are still experiencing this issue, please change the version to Fedora 26. If you experience different issues, please open a new bug report for those. I confirm that on Fedora 25 with kernel 4.9.3 the issue still persists. [ 7.792097] iwlwifi 0000:02:00.0: Microcode SW error detected. Restarting 0x2000000.

That worked for me on a Thinkpad P50, Intel Corporation Wireless 8260 (rev 3a) Upgraded from Fedora 24 to 25 (kernel 4.10.5-200), wireless was broken. Workaround: remove iwlwifi-8000C-22.ucode from /lib/firmware and reboot Wireless is now working. Cause and solution found! The iwlwifi-8000C-22.ucode has been corrupted in the upstream when originally uploaded on 2016-07-10. It was later updated on 2017-01-07. The updated version works. See https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/log/iwlwifi-8000C-22.ucode While the file have the same size, they are NOT identical. The working version can be downloaded here: https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/tree/iwlwifi-8000C-22.ucode Please update iwl7260-firmware.noarch pulling latest of iwlwifi-800C-22.ucode to fix the problem permanently.

There is an improvement - it's possible to NOT experience a firmware crash with the updated version but crashes are still possible. 27.ucode that is available from the upstream is not compatible with the the iwlwifi driver that currently ships with F25 kernel - it requires CoreLinux24. https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git/log/?h=release/LinuxCore24 s/as opposed to/same as/ I can also confirm that CoreCycle19_stab@391740 still has the same issue. ThinkPad P50, 4.9.14-200.fc25.x86_64. Removing 22.ucode so that 21.ucode is loaded still seems to be the workaround.. Perhaps the bug summary needs to be changed back? I got the driver from the intel repo, not the testing RPM.

(In reply to Arcadiy Ivanov from comment #41) > What link did you get the intel version from? $ git remote -v origin https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git Same with kernel 4.11.3-202.fc25.x86_64 and iwl7260-firmware 25.30.13.0-72.fc25. This bug has in fact gotten worse, with a major regression starting around kernel 4.10.x, because the kernel doesn't recover gracefully from the firmware error; all processes accessing the network interface end up in a frozen unkillable state and a clean shutdown is no longer possible. See also https://bugzilla.kernel.org/show_bug.cgi?id=195299 which discusses the kernel bug. If you have an iwl8265, the latest firmware for that card (and kernel 4.11.x) no longer crashes, but the bug is still present with iwl7260 even with the latest kernels. The last kernels I am able to use successfully (i.e., the firmware crashes but I can recover from the crash by switching wi-fi off and back on) are the 4.8.x series (haven't tested carefully if any of the early 4.9.x might still be ok, the late 4.9.x are broken, all the 4.10.x are broken, and 4.11.4 is still broken).

dmesg with kernel 4.11.3, Intel 7260 AC, firmware 17.459231.0
Just to show the problem is still present with kernel 4.11.x, for the Intel 7260 at least. Note how the SYSASSERT causes the kernel to oops and the system can't recover gracefully (unlike the 4.8.x kernels which are fine).
I can confirm the bug appears on F26 after upgrade from 25 (which worked for me - Lenovo T430s). same bug here, when trying to establish an access-point/shared to others wifi network on kernel 4.12.11-300.fc26.x86_64 using a lenovo T440p laptop. some dmesg samples: [18867.704871] WARNING: CPU: 7 PID: 981 at drivers/net/wireless/intel/iwlwifi/mvm/tx.c:1360 iwl_mvm_rx_tx_cmd+0x88b/0x980 [iwlmvm] [18867.704871] Modules linked in: nf_nat_h323 nf_conntrack_h323 nf_nat_pptp nf_nat_proto_gre nf_conntrack_pptp nf_conntrack_proto_gre nf_nat_tftp nf_conntrack_tftp nf_nat_sip nf_conntrack_sip nf_nat_irc nf_conntrack_irc nf_nat_ftp nf_conntrack_ftp fuse xt_nat veth xfs vboxpci(OE) vboxnetadp(OE) vboxnetflt(OE) vboxdrv(OE) ccm rfcomm ipt_MASQUERADE nf_nat_masquerade_ipv4 xt_addrtype ip6t_rpfilter br_netfilter ip6t_REJECT nf_reject_ipv6 xt_conntrack ip_set nfnetlink ebtable_nat ebtable_broute bridge stp llc ip6table_nat nf_conntrack_ipv6 nf_defrag_ipv6 nf_nat_ipv6 dm_thin_pool dm_persistent_data dm_bio_prison ip6table_mangle loop ip6table_raw ip6table_security iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack libcrc32c iptable_mangle iptable_raw iptable_security ebtable_filter [18867.704898] ebtables ip6table_filter ip6_tables cmac bnep sunrpc btusb btrtl btbcm uvcvideo btintel bluetooth videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_core videodev cdc_acm media ecdh_generic arc4 mei_wdt intel_rapl iTCO_wdt iTCO_vendor_support x86_pkg_temp_thermal intel_powerclamp coretemp iwlmvm kvm_intel mac80211 kvm snd_hda_codec_realtek irqbypass intel_cstate snd_hda_codec_hdmi snd_hda_codec_generic iwlwifi intel_uncore intel_rapl_perf snd_hda_intel cfg80211 snd_hda_codec snd_hda_core snd_hwdep snd_seq rtsx_pci_ms memstick joydev snd_seq_device snd_pcm mei_me i2c_i801 lpc_ich mei snd_timer shpchp thinkpad_acpi ie31200_edac snd soundcore rfkill tpm_tis tpm_tis_core tpm dm_crypt cdc_mbim cdc_ncm usbnet hid_logitech_hidpp mii cdc_wdm i915 rtsx_pci_sdmmc mmc_core i2c_algo_bit [18867.704933] drm_kms_helper crct10dif_pclmul crc32_pclmul crc32c_intel ghash_clmulni_intel e1000e drm serio_raw rtsx_pci ptp pps_core wmi video hid_logitech_dj [18867.704941] CPU: 7 PID: 981 Comm: irq/34-iwlwifi Tainted: G W OE 4.12.11-300.fc26.x86_64 #1 [18867.704942] Hardware name: LENOVO 20AN006VGE/20AN006VGE, BIOS GLET74WW (2.28 ) 10/21/2014 [18867.704943] task: ffff8b0c24cf25c0 task.stack: ffffb30b424f8000 [18867.704949] RIP: 0010:iwl_mvm_rx_tx_cmd+0x88b/0x980 [iwlmvm] [18867.704949] RSP: 0018:ffffb30b424fbcc8 EFLAGS: 00010202 [18867.704951] RAX: 0000000001051010 RBX: ffff8b0c29d45568 RCX: 0000000000001d2f [18867.704951] RDX: 0000000000001d2e RSI: ffff8b0c3e3de7e0 RDI: ffffe76890a72180 [18867.704952] RBP: ffffb30b424fbd40 R08: 000000000001e7e0 R09: ffffffffc0a7602c [18867.704953] R10: ffff8b0a19f70e30 R11: ffffffffb444bc20 R12: 0000000000000088 [18867.704954] R13: 0000000000000050 R14: ffff8b0a19f70e00 R15: ffff8b09d98f7000 [18867.704955] FS: 0000000000000000(0000) GS:ffff8b0c3e3c0000(0000) knlGS:0000000000000000 [18867.704956] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [18867.704957] CR2: 00007fb6efa0a3e0 CR3: 0000000310e09000 CR4: 00000000001406e0 [18867.704958] Call Trace: [18867.704976] ?

Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. Bug still exists in F27, please update Fedora version in bug header. |
