Title:
Xorg uses max CPU after drm:i915_hangcheck_hung
Status in “xorg” package in Ubuntu:
Expired
Bug description:
Hi guys,
apprently my box overheats under high load with more-than-moderate
environment temperatures, which triggers the kernel (correctly!) to
throttle the CPU. Apparently, this throttling (or some data
transfer/DRM issue?) causes the GPU to hang/lose communication (kernel
bug? see dmesg. MCE is just talking about temparature recovery), which
causes Xorg to misbehave.
Both displays go black (from top to bottom, one after another), and
come back again, and after that everything is horribly slow, Xorg uses
90something% of the CPU, and otherwise everything seems fine.
Switchtig to a VT is bearible and stops Xorg from using CPU, killing
it makes lightdm bring it up again and everything is seemingly fine.
Same behaviour repeats soon unless load conditions are relaxed.
So, this might be two bugs: one for the kernel to let the GPU hang /
don't handle this more smartly; one for Xorg to start consuming CPU
like crazy after this happened.
Please link this bug to the proper packages, and maybe link it to
other i915_hangcheck bugs, too.
Cheers,
count
