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.
