After reverting kernel from 3.5.0 to 3.2.0-32-generic, the bug went away.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.7 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

During my experiments with kernel 3.2.0, the xorg also crashed. I had to disable X11 acceleration for 3.2.0 kernel to work.
Same story with kernel 3.5.0. This means that I erred on comment #2 where I claimed that simple reversal to 3.2.0 fixed the problem. Apparently I forgot to mention that somewhere inbetween I disabled X11 acceleration.

For what it worth, I tested the 3.7.0-030700rc2-generic kernel and found that it behaves the same way as the 3.2.0 and 3.5.0 kernels - e.g. there is no difference between them (from the bug's perspective).

Before upgrade to ubuntu 12.10, both kernel (3.0.0 I guess) and X11+acceleration worked properly.

I will update the bug's title to represent the fact.

I guess this is a duplicate of bug #1066464.
