Description: Ubuntu 14.04.1 LTS
Release: 14.04
apt-cache policy xserver-xorg-video-intel
xserver-xorg-video-intel:
Installed: (none)
Candidate: 2:2.99.910-0ubuntu1.1
System: Shuttle XPC SZ77R5 with 32 GB of memory installed (x4 8GB matched kit
of sticks).
Processor: Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz
Kernel: 3.13.0-35-generic #62-Ubuntu SMP
I am experiencng random lock-ups/crashes when using this system and the
i915 video driver is active. This results in a fully corrupted screen
and no ability to do anything. The only remedy is to restart the system
by holding down the power button. I have tried a number of different
ideas from different bug reports but they all seem to be different
regarding the i915 driver. The screen corruption can be seen in the
attached grab.
My last resort to see if it was this driver being responsible was to
remove it from the system and make use of the regular vesa drivers. I
have been using the vesa driver for a week now with no further crashes.
All memory sticks are confirmed as good. I have maxed out the memory
running 8 different virtual machines to prove to myself there wasn't a
bad stick of memory. Also memtest86+ does not show any faults.
This problem has been apparent from kernel 3.2.x right up to not with
3.13.x installed. At various points I did test with kernels from
Liquorix to see if the problem was resolved (or in the kernel at all).
The crashes have happened in Gnome and KDE with different window
managers which suggests it's related to xserver (driver).
The crashes can come at any time under any kind of load. Sometimes just
scrolling a window or entering some text. The only constant seems to be
that something on the screen has to change. If left alone with no
interaction the machine would run just fine. I have used it remotely
with X forwarding without problem.
This definitely seems to be an i915 issue, or something closely related to it.
