Description Alexander Hunziker 2012-10-07 22:30:17 UTC

Description of problem:
I tried to connect to my home wifi, this failed and brought up the bug reporting tool. I also have Arch Linux running which shows the same issue when running kernel 3.6, but not when running kernel 3.5 so my guess would be that one of the changesets inbetween caused this problem.

Additional info:
libreport version: 2.0.14
abrt_version:   2.0.13
cmdline:        initrd=/ubninit root=UUID=FA71-7624 rootfstype=auto ro rd.live.image quiet  rhgb rd.luks=0 rd.md=0 rd.dm=0 BOOT_IMAGE=/ubnkern 
kernel:         3.6.0-0.rc6.git0.2.fc18.x86_64

Comment 1 Stanislaw Gruszka 2012-10-23 13:55:16 UTC

I believe this problem is fixed by 3.6.3-2 kernel:
http://koji.fedoraproject.org/koji/buildinfo?buildID=361643
Please test.

Comment 2 Stanislaw Gruszka 2012-11-02 15:17:43 UTC

I hope this is fixed, if not please reopen this bug.

Comment 3 Alexander Hunziker 2012-11-03 22:14:45 UTC

A nightly spin from October 30 still shows this problem, unfortunately.

Comment 4 Alexander Hunziker 2012-11-04 22:07:04 UTC

A stock kernel 3.6.5 doesn't show this issue any more though.

Comment 5 Stanislaw Gruszka 2012-11-06 08:52:17 UTC

Ok.
