Description of problem:
After updating from kernel-3.11.10-301.fc20.x86_64 to kernel-3.12.5-302.fc20.x86_64 system started to hang on many occasions while best reproducer is to just run gnome-control-center. The hang is complete lockup as even sysrq does not work to get anything out of system.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Get lenovo T420s as it seems to be HW dependant and install F20 there.
2. Run gnome-control-center and it locks up.
3. Boot up with nomodeset and system works fine except ugly graphics.
System hang I'd appreciate any hints to how to get reasonable debug out of it.
Works fine with rawhide kernel (kernel-3.13.0-0.rc4.git5.1.fc21.x86_64)
Same problem on Lenovo ThinkPad T520.
Same problem with kernel.x86_64 0:3.12.6-300.fc20.

intel and nvidia cards are both on
Thanks. Based on some other reports that look similar, let's go with nouveau. If you can get a backtrace somehow, that would probably be rather helpful. Perhaps installing kernel-debug would result in that.
Well I played with it today, network card stays on and sshd does respond but fails to open session. I also can't see any complaining from kernel in dmesg/messages after checking journalct -r and the most funny part kernel-debug fixes the issue. I'm unable to reproduce issue while having kernel-debug installed.
xrandr --prop does reproduce the issue.

netconsole output after hang

I suppose this goes away with "nouveau.runpm=0" in your kernel boot options?
I have just tried with nouveau.runpm=0 and system hangs .

That's, er, strange, considering the previous backtraces.... Can you get me new logs?
I don't have log or backtrace. Gnome freeze at all and also logging stop.
I have opened this ticket https://bugzilla.redhat.com/show_bug.cgi?id=1049294 marked as duplicate of current. Never sent backtraces before.
I have just modified in the grub.cfg following line:
linux /vmlinuz-3.12.6-300.fc20.x86_64 root=/dev/mapper/fedora-root ro rd.lvm.lv=fedora/swap rd.luks.uuid=luks-432afd15-3606-4b99-a28d-a31285d41172 vconsole.font=latarcyrheb-sun16 rd.lvm.lv=fedora/root nouveau.runpm=0 rhgb quiet
Maybe it's the wrong way.
Now I'm working with kernel 3.13.0-0.rc7.git0.1.fc21.x86_64 and everything is going well.
With nomodeset in kernel 3.12.6-300.fc20.x86_64 is working but heavy cpu load.
I made a mistake. Written nuveau in grub.cfg instead of nouveau.....
Sorry for the mistake... checked and tested with nouveau.runpm=0 and everything work fine with kernel 3.12.6-300.fc20.x86_64.
Same problem through 3.12.6 to 3.12.8 on Thinkpad T420. I am now stick on 3.11.10
the 3.12.7 kernel should resolve this problem
Just tried one hour ago on thinkpad 430 with kernel 3.12.8 without nouveau.runpm=0 on the grub2.cfg and system hangs like before.
I confirm this problem on a Thinkpad T420s. The problem is still present both in kernel-3.12.9-301.fc20.x86_64 and in kernel-3.12.10-300.fc20.x86_64 from updates-testing.
In both cases adding nouveau.runpm=0 in grub2.cfg fixes it. Just, in my case the problem it is straightforward to reproduce the problem: it just suffices to launch gnome-control-center and the system immediately freezes
I have compiled kernel 3.13.2 from koji and installed it
The problem seems to have been fixed there.
I consider this fixed, thanks.
