Nouveau - Oct 2012 - [Bug 55596] New: weston-launch causes graphical corruption / lockup

https://bugs.freedesktop.org/show_bug.cgi?id=55596

          Priority: medium
            Bug ID: 55596
          Assignee: nouveau at lists.freedesktop.org
           Summary: weston-launch causes graphical corruption / lockup
          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: vekinn at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/DRI/nouveau
           Product: Mesa

Using the nouveau linux-2.6 branch and git mesa/libdrm

When I run weston-launch 1&> output
The screen displays white and black blocks with garbled images and is
unresponsive.  I can not switch tty nor ctrl+alt+backspace.  I shutdown with
ACPI power button.

dmesg does not appear to show any errors and the output of weston-launch
appears normal.

The same happens on regular 3.5 and 3.6 kernels with nouveau built in.

The ACPI power button does a soft shutdown that works normally.

Above patch had hit Linus' tree 2 days ago. It will be part of Linux
3.7-rc3.
Thanks for reporting.
