Comment 1 Takashi Iwai 2014-11-05 16:29:44 UTC

Which kernel version?  Does the problem still remain in the 13.2 release kernel?
If yes, could you check whether 3.17 or 3.18 still has the same problem?
If it's not fixed, we need to report to upstream.  Thanks.

Wifi was dead a few minutes, then it apparently reconnected and worked again.
Which kernel package should I try exactly?

Comment 3 Takashi Iwai 2014-11-20 20:52:04 UTC

At first try the kernel in OBS Kernel:openSUSE-13.2 repo.  It already contains the backport to stabilize iwlwifi issues.

If it still doesn't work, give hwinfo output, and check Kernel:stable and Kernel:HEAD repos.

Comment 4 Ludwig Nussel 2014-12-06 12:28:18 UTC

3.16.7-13.gb834837-desktop doesn't help. It doesn't dump the excessive debug output like before but there are still hangs.

Comment 5 Takashi Iwai 2014-12-06 17:15:39 UTC

Please give the full hwinfo output, not the stripped one.  Also give the full dmesg output, too.

In anyway, try the kernel package in OBS home:tiwai:os13.2-ckt1 repo.  This contains backports by Ubuntu and it has a couple of more iwlwifi-related fixes.

Doesn't help either.

Comment 8 Takashi Iwai 2014-12-11 10:56:39 UTC

Then the only hope is to try 3.18 kernel with the latest kernel-firmware package including the iwlwifi firmware udpates.  If the same problem still happens there, please report it to bugzilla.kernel.org.

Comment 9 Takashi Iwai 2014-12-14 08:46:47 UTC

I found that kernel-firmware package on 13.2 was a snapshot of 20140903, while there was an update of iwlwifi firmware after that (Sep 12).  Could you just try to upgrade kernel-firmware package from FACTORY before trying other kernel packages?

Comment 10 Ludwig Nussel 2014-12-22 16:13:17 UTC

It's much better with the updated firmware. There are still hangs every once in a while. The "changed bandwidth" lines are still in dmesg but cause no issue usually.

If this still occurs, please reopen.
