[Bug 1367825] Re: Intel i915 video driver causing random crashes on i7 Z77 system
THis log file shows the intel driver being loaded. Since I uninstalled
the intel driver and have been running on VESA I have not had a single
crash. Over a month now.
The log file attached is older (April) as I had saved it. I cannot
revert to running the intel package right now as I have tasks running,
but the log file is identical bar the date.
** Attachment added: "Old Xorg log."

Title:
Intel i915 video driver causing random crashes on i7 Z77 system
Status in “xserver-xorg-video-intel” package in Ubuntu:
Confirmed
Bug description:
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.
