           Summary: Nouveau. Screen corruption and occasional gpu lockup
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.2.2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri at kernel-bugs.osdl.org
        ReportedBy: cucullus at mail.ru
        Regression: Yes


After upgrade to kernel 3.2 nouveau driver produces corrupted image in X. On
bottom part of screen (~1/3) controls are invisible (some of them become
visible after mouse hover or scroll).

Switching to console seems to be slower than earlier. Occasional gpu lockup
occurs. Console works fine.

Revert to 3.1 solves problem.
