I'm also struggling with this issue for a while now. I had the random
crash during 2012, it stopped as soon as i stopped using Unity3D /
compiz.

Also worth mentioning is that I'm also getting i915 related errors in

Okay, i'm using my laptop with 6 GB of ram for some time now. No issues
at all.. my computer also never swaps now... i guess that this issue
comes only when computer starts to swap memory to the hard disk .. i
have similar problem on my desktop with totally different intel chipset
but there
i'm getting suspicious about this issue... i've upgraded memory on my laptop
and i feel that it works better now... i wonder how much memory do you guys
have... i think that issue always come to the surface when the system starts to
swap memory to the hard disk.
I'm gonna investigate this more
I would like to help with much as I can... but nobody is really interested
about that. I know that there are lot of bugs. But this one makes computer
unusable! Some of us are discussing it here and want to help... but we dont
know yet how many other people already swithed to Windows or other
This is the state of Linux at the moment. Complete hard-lockups on
multiple computers/cpus completely ignored.
Thanks Intel and kernel developers, back to Windows 7 yet again.

Really nobody is interested in fixing this issue? I would like to help but I

would like to help. My new laptop is in the bag most of the time because I
can't use it...
Please can somebody respond that we begin

Today I experienced a complete lock up of the machine with kernel
3.4rc2, only a few minutes after booting. The only program that was
running was Team Viewer 6.
After resetting the machine, the issue did not return and I also was not
prompted by Apport to file a bug.

Well this is interesting. I've just been working for about an hour and a
half with kernel 3.2.0-23 without experiencing a single lock up.
The load issue is still there though, but at least now I am able to get
some work done. Now let's see how well this kernel deals with

Thanks Matt, let me know how it goes after the update. If the issue is

have any wisdom to share.

Well after rebooting, the situation seems to be a lot better. With the
previous kernel (or perhaps before the updates were applied) I would
have experienced several lock ups by now, but right now it has not
failed even once. Of course this is after running for less than half an
hour, so I guess

Thanks for continuing to file the gpu lockup bugs. Reviewing all of
them (including your manually collected dumps), it is always the same -
zero error codes and the WARNING message above. Thinking the latter may
be the most relevant bit.
Next step is probably to forward this upstream. Before
