Title:
Gpu hung on i915.
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hello,
my gpu, an old GMA945 on i915, randomly crashes.
This is an extract of the kernel log reporting the crash.
I have to admit, to be precise, that this defect has been occuring just after
upgrading to 15.10 and kernel 4.x; before of that, with ubuntu 15.04, it never
occurred.
Thanks.
