            Bug ID: 96345
           Summary: Intermittent GPU Crashes on Ubuntu 16.04

Zip file containing aforementions logs (dmesg * 2, GPU dump * 2)

Various programs (xorg, compiz, java) have begun having intermittent GPU hangs
that sometimes result in crashes.  I've attempted to narrow this down to
perhaps a kernel upgrade (from the ubuntu 4.4.0-21 to 4.4.0-22) but running
with the old kernel the hangs persist.  I've also tried other various
workarounds I've found online for similar bugs but the problem almost always
persists (one exception noted below).  Additionally, I've tried disabling
intel-microcode and using the generic display drivers.

Notably, they occur most frequently during heavy opengl use (and primarily when
I am playing Minecraft).

Another notable fact is that I recently upgraded the amount of RAM in my system
from 3 GB to 8 GB and have an integrated chipset (Ironlake Mobile, gen 5, I
believe).  I have not tried downgrading the amount of RAM my system has as
everything else works fully (and a memtest shows no problems with the modules).

I've attached a few dmesg logs and gpu dumps in case they might be of use. 
Additionally, my `uname -a` is as follows:

"Linux Xaos-HP 4.4.0-22-generic #40-Ubuntu SMP Thu May 12 22:03:46 UTC 2016
x86_64 x86_64 x86_64 GNU/Linux"

Finally, I should note that I am not using the built in display of the laptop,
but rather a 1080p monitor (TV) connected via HDMI.

As to the previously mentioned exception:  when minecraft is run as follows the
problem seems to go away, but rendering speed is practically nullified.

`env always_flush_cache=true always_flush_batch=true java -jar Minecraft.jar`

(And I've read that apparently when certain crashes with Minecraft occur and
have the outputs listed below this text that your graphics chipset is not
capable of running Minecraft.. but I've done so before with no problems on
ubuntu distros 12.04, 13.10, 14.04, and 16.04 prior to my RAM upgrade. 
Additionally, other system components like xorg and compiz have been affected
by the bug so I don't believe Minecraft is the sole problem.  Just something
that has been most notably affected due to the amount of rendering that an
opengl game would possess.

"[B#347] 2016/05/28 19:40:14 [INFO]  intel_do_flush_locked failed: Input/output
error
[B#347] 2016/05/28 19:40:14 [INFO]  AL lib: (EE) alc_cleanup: 1 device not
closed" )

Again, I can run more system commands to provide information if needed, but I'm
unsure which ones would be useful so I will belay attaching any additional
information until it is requested.

Attached files (located in a zip):
     dmesg1 - First sample dmesg log
     error1 - GPU Dump associated with dmesg1
     dmesg2 - Second sample dmesg log
     error2 - GPU Dump associated with dmesg2
