Public bug reported: 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.
