Screen corrupted, "[TTM] Out of kernel memory"

[Stilor]

Description: Ubuntu 12.10
Release: 12.10

After upgrading from Precise to Quantal Kubuntu, some applications cause the screen to become corrupted. If I switch to text console by Ctrl-Alt-F1, there's lots of the following messages running on the screen:

[ 1260.017979] [TTM] Out of kernel memory

One such application is 'easytag', it is typically causing such misbehavior within 2-3 minutes after startup. Killing the offending application makes everything go back to normal.

The following is a report on kernel.org's bugzilla which seems relevant:

https://bugzilla.kernel.org/show_bug.cgi?id=43751

I also use nouveau driver (GeForce 8600M GS). Precise Pangolin's kernel (3.2.0-34) did not exhibit this problem; the Quantal's kernel (3.5.0-19) does.

Status changed to 'Confirmed' because the bug affects multiple users.

This happens also with the radeon driver in both 12.10 and 13.04.

Stilor, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc6

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
