Description Jan Pokorný [poki] 2017-11-27 14:13:22 UTC 
Using kernel 4.15.0-0.rc0.git7.2.fc28.x86_64, I could not get this wifi
card present in Lenovo T460p working with iwl7260-firmware-25.30.13.0-70.fc28.
Downgrading back to -78 fixed the issue (which is also present with -80).

It seems to boil down to iwlwifi-8265-34.ucode file being present with
the those newer packages (and getting priority in some kind of fallback
scheme) while it is not with -78.

Bad boot (with -80):

Apparently, I could prevent iwlwifi-8000C-34.ucode being selected one
way or the other, but that would not be too systemic.

Comment 2 Pavel Roskin 2017-11-30 18:00:30 UTC 
I'm seeing a similar error with the kernel test day image: https://fedoraproject.org/wiki/Test_Day:2017-11-30_Kernel_4.14_Test_Day

WiFi is not working. WiFi is working on the same machine with Fedora 27 4.13 kernels.

Dell Precision 7510, x86_64.

$ uname -a
Linux localhost 4.14.2-300.fc27.x86_64 #1 SMP Tue Nov 28 00:29:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

I've attached the kernel log.
Comment 3 Pavel Roskin 2017-11-30 18:14:47 UTC 
WiFi starts working after removing /lib/firmware/iwlwifi-8000C-34.ucode and reloading the modules (iwlmvm and iwlwifi). Apparently the version 34 of the firmware is bad or incompatible with the driver.

Comment 4 Jacobo Cabaleiro 2017-11-30 21:22:46 UTC 
Identical situation with kernel from test day (https://fedoraproject.org/wiki/Test_Day:2017-11-30_Kernel_4.14_Test_Day) in F27, same 8260 (rev 3a).

In my case error looks like this:

Comment 5 Vít Ondruch 2017-12-01 09:52:08 UTC 
I observe the same issue. Downgrading to -78.
Comment 6 Vít Ondruch 2017-12-01 09:58:02 UTC 
Interestingly, with the -80 linux-firmware, my laptop even does not restart correctly. It hangs at some UEFI initialization phase.
Comment 7 Jan Pokorný [poki] 2017-12-01 18:03:28 UTC 
For the record, I am using legacy BIOS to boot.
Comment 8 Pavel Roskin 2017-12-01 18:42:35 UTC 
The fix is in Linux mainline:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dac4df1c5f2c34903f61b1bc4fc722e31b4199e7

It is also in Linux 4.14.3:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/log/?h=linux-4.14.y

The workaround for now is to move /lib/firmware/iwlwifi-*-34.ucode to another directory.

*** Bug 1520071 has been marked as a duplicate of this bug. ***
Comment 10 Josh Boyer 2017-12-04 13:18:48 UTC 
This is a kernel bug.  Should be fixed in rawhide already and f27 and older will be getting a 4.14.3 rebase soon.
Comment 11 Jan Pokorný [poki] 2017-12-14 23:10:44 UTC 
Confirming it started to work again with 4.15.0-0.rc2.git2.1.fc28.x86_64
at latest (had iwl7260-firmware suppressed from updates for a bit).
