After trying to loade the nouveau driver on my laptop my laptop starts to stop updating the display and reacting to the keyboard or mouse. The laptop seems to work though, at least I saw some disc activity through the LED.

uname -a: Linux pingu 3.17.0-rc1 #2 SMP PREEMPT Mon Aug 25 20:04:39 CEST 2014 x86_64 Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz GenuineIntel GNU/Linux

if needed I can provide the kernel config file and other information.

I put it to Video(DRI - non Intel), because I only encounter this error while loading nouveau, but it could be an error somewhere else, maybe 3.17 related, though I get the same behaviour on 3.16.1 but without the pm_runtime_work thread dying.

while bisecting the kernel to find the commit which causes the stack. I noticed that this stack is only triggered through some CPU load and not always. Maybe this new log helps little bit more
