Package: kernel Architecture: x86_64 OS Release: Fedora release 17 (Rawhide) Comment ----- boot computer Package: kernel Architecture: x86_64 OS Release: Fedora release 17 (Rawhide) Comment ----- booted system, logged in to G-3 shell, thunderbird auto started and was watching mailboxes fillup when msg in notification area of a kernel problem this should be fixed by commit c6a21d0b8d667f403bc6186ef215a504a26ab682 in Jreodel's iommu tree. Not sure if thats been pulled in yet. Can you try to apply that patch please and see if the problem goes away?

Can you try to > apply that patch please and see if the problem goes away? That patch should be in the -git6 kernel already in rawhide. Neil, does bug 751797 look like the same issue to you? Its the same symptom for certain, I can guarantee the same root cause however. This one looks particularly odd because the device address isn't aligned to any sane boundary. Clyde, can you reproduce this at Will? If so, I'll come up witha stap script to help you diagnose this.

Clyde, any info from the instrumented kernel build that Neil did in bug 751797 ? *** Bug 751964 has been marked as a duplicate of this bug. *** (In reply to comment #7) > Clyde, any info from the instrumented kernel build that Neil did in bug 751797 > ? I am very sorry, but I wasn't able to understand the use of the script. I still see the error in rawhide kernels, not F16. I built you a kernel in that bug, not a script clyde. All you have to do is install it and reboot. Also in comment 9 of https://bugzilla.redhat.com/show_bug.cgi?id=751797 Sorry for the confusion. Too easy to do and so it was hard for me, :-) [ 120.955135] ------------[ cut here ]------------ [ 120.955153] WARNING: at lib/dma-debug.c:1041 check_sync+0x56c/0x5f0() [ 120.955156] Hardware name: P5K-E [ 120.955159] sky2 0000:02:00.0: DMA-API: device driver tries to sync DMA memory it has not allocated [device address=0x00000001063d8040] [size=60 bytes] [ 120.955163] Modules linked in: fuse lp parport ebtable_nat ebtables ipt_MASQUERADE iptable_nat nf_nat xt_CHECKSUM iptable_mangle tun bridge stp llc lockd nf_conntrack_netbios_ns nf_conntrack_broadcast ip6t_REJECT nf_conntrack_ipv4 nf_defrag_ipv4 nf_conntrack_ipv6 nf_defrag_ipv6 ip6table_filter xt_state nf_conntrack ip6_tables raid1 uvcvideo snd_usb_audio snd_usbmidi_lib snd_rawmidi snd_seq_device snd_hda_codec_hdmi snd_hda_codec_analog videodev joydev media v4l2_compat_ioctl32 snd_hda_intel snd_hda_codec snd_hwdep sky2 microcode serio_raw snd_pcm iTCO_wdt snd_timer snd i2c_i801 iTCO_vendor_support soundcore snd_page_alloc asus_atk0110 configfs virtio_net kvm_intel kvm sunrpc uinput raid10 btrfs zlib_deflate libcrc32c ata_generic pata_acpi firewire_ohci firewire_core crc_itu_t pata_jmicron radeon ttm drm_kms_helper drm i2c_algo_bit i2c_core [last unloaded: scsi_wait_scan] [ 120.955259] Pid: 2651, comm: setiathome-5.28 Not tainted 3.2.0-0.rc1.git2.1.fc17.x86_64 #1 [ 120.955262] Call Trace: [ 120.955265] <IRQ> [<ffffffff8107ceaf>] warn_slowpath_common+0x7f/0xc0 [ 120.955276] [<ffffffff8107cfa6>] warn_slowpath_fmt+0x46/0x50 [ 120.955284] [<ffffffff81326efc>] check_sync+0x56c/0x5f0 [ 120.955289] [<ffffffff81312e8e>] ? random32+0x2e/0x40 [ 120.955293] [<ffffffff81327352>] debug_dma_sync_single_for_cpu+0x42/0x50 [ 120.955299] [<ffffffff811930ec>] ? ksize+0x1c/0xc0 [ 120.955303] [<ffffffff813229cc>] ? is_swiotlb_buffer+0x3c/0x50 [ 120.955307] [<ffffffff813231e8>] ? swiotlb_sync_single+0x38/0x80 [ 120.955312] [<ffffffff8132332c>] ? swiotlb_sync_single_for_cpu+0xc/0x10 [ 120.955322] [<ffffffffa0371ff3>] sky2_poll+0x573/0xd90 [sky2] [ 120.955329] [<ffffffff81109672>] ? check_for_new_grace_period+0xc2/0x160 [ 120.955335] [<ffffffff815472f1>] ? net_rx_action+0xa1/0x460 [ 120.955339] [<ffffffff815473b9>] net_rx_action+0x169/0x460 [ 120.955344] [<ffffffff81020cc9>] ? sched_clock+0x9/0x10 [ 120.955351] [<ffffffff810aba75>] ? sched_clock_local+0x25/0x90 [ 120.955357] [<ffffffff810859b8>] __do_softirq+0xc8/0x3a0 [ 120.955367] [<ffffffff810aba75>] ? sched_clock_local+0x25/0x90 [ 120.955372] [<ffffffff81687ebc>] call_softirq+0x1c/0x30 [ 120.955378] [<ffffffff8101b385>] do_softirq+0xa5/0xe0 [ 120.955381] [<ffffffff81085fee>] irq_exit+0xbe/0xf0 [ 120.955385] [<ffffffff81688793>] do_IRQ+0x63/0xe0 [ 120.955392] [<ffffffff8167d633>] common_interrupt+0x73/0x73 [ 120.955394] <EOI> [<ffffffff8167d6d9>] ? retint_swapgs+0x13/0x1b [ 120.955400] ---[ end trace 9ea8b974ec78d8cd ]--- as per last comments in 751797, closing this as a dup *** This bug has been marked as a duplicate of bug 751797 *** |
