[Original Description]
This happens when I play the game Minecraft in 11.10 Oneiric. To be honest, I don't know if it is my video card, Java, or my processor that is the problem. When I run Minecraft, Java usually crashes after a few minutes. And not just Java, it usually beings down a few other processes with it. I could run this fine in 11.04. After Java crashed this time, Apport had me report this bug. Also, after Java crashed this time, Unity also crashed, so I currently  have no panels or window decorations. I'll reboot and try to crash it all again, and see if I can get some more useful information. All I know is that Java consistently crashes in Oneiric while running Minecraft on my system, and almost always causes more problems when it crashes.

This should be amenable to bisection, if you fancy the challenge.

It is kind of difficult to get it to happen at the same time. For
example, last night it crashed twice, within two minutes of starting the
game. Today, it crashed twice only after the game had been running for
ten or fifteen minutes. And by 'crash twice' I mean, two separate
incidents. The time and cause of the crash seems somewhat random. The
only thing that is not random is the fact that it always crashes. Also,
I'm having difficulty getting the logs, because after it crashes, Unity
also goes down most of the time, so I have to reboot, which seems to
clear the Xorg logs. Perhaps I could try running it in a Desktop
Environment other than Unity, which is already pretty unstable at this
point.

What do you mean by "This should be amenable to bisection, if you fancy
the challenge."?

It means, you could probably narrow the bug down by following the steps
documented here:

  https://wiki.ubuntu.com/Kernel/KernelBisection

You know that it worked in natty, so take as your starting point
"2.6.38", and end point "3.0.0".

As a shortcut, or if  building things from git looks like *too* much of
a challenge, there are some pre-built kernel .debs at
http://kernel.ubuntu.com/~kernel-ppa/mainline/, though this won't get
you down to the exact commit.

Alright, I am going to try to bisect this. I was wanting to work on

than have me test them?

Hi Corbin,

I wish we could pre-build all the kernels to make this easier, and maybe
one day we will but unfortunately we're not really set up for that
currently.  So, sorry...  we'll try to be available for questions though
(but be aware the next couple weeks are crunch time for getting oneiric
finalized.)

i915_error_state after a gpu hang on SNB

Hello everyone,

i do also get hangs with minecraft - however i have a Intel(R)
Sandybridge Mobile (GT2+) running  3.1-rc6+ (drm-intel-next git
64a742fac3a22f57303d8f1b7e347350a1c48254)

I can run minecraft, but after some time i get a gpu hang. dmesg then
says:


[18291.377254] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[18291.377262] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state

Said /debug/dri/0/i915_error_state is attached.

If i need to provide more informations, feel free to ask.

Thanks for your help,
Michael

Michael,

Though in the same game, your hang on Sandybridge turned out to be
unrelated.  I fixed it today in Mesa master:

commit 3cc0a7be23ab603ed40d602595f673a44e079885
Author: Kenneth Graunke <kenneth@xxxxxxxxxxxxx>
Date:   Fri Oct 21 01:03:37 2011 -0700

    i965: Apply post-sync non-zero workaround to homebrew workaround.

The fix should appear in Mesa 7.11.1.

However, that doesn't resolve Corbin's original issue on GM45.  This bug
report continues to track that.

Kenneth,

i can confirm that this fixes my problem. I just updated mesa from git,
and played for some time without crashes.

Too bad that this doesnt fix things for Bryce - good luck that the
problem will be fixed soon :)

Thanks for your work Kenneth!

Michael

Good morning, 
This bug does still exist. After about an hour of testing, my tester's game-play was ended by a GUP hang (see attached terminal output).  

Before this was reproduced, there was a similar problem, which may or
may not be related. Because I have no idea what happened, I'll talk
about it here. While the tester was playing, the X server crashed, and
the screen switched to a TTY-like session with kernel messages about the
error, and the kernel seems to have completely crashed. I believe that
the kernel crashed because the computer was taking no input. I couldn't
switch TTY Sessions or anything, I just had to do a hard reboot. Because
I had no X server,  the only valuable output I could get was by taking
pictures of the screen with my cell phone. I uploaded the images to my
site here: http://jdgregson.com/temp/ubuntubug/ It may be important to
note that this error occurred while the tester was using the guest
session included in lightdm.

Hope this helps.
