           Summary: X server crash DMA hang
           Product: xorg
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: high
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: nick at ukfsn.org
         QAContact: xorg-team at lists.x.org


I occasionally get a server crash:

DMA queue hang:  dmaPut=15, current=bc, status=0

I first thought this was Adobe flash related, as it has never happened with GNU
Gnash, but today it happened whilst switching workspaces in Fluxbox.  It
appears to manifest after a two to three days Xserver uptime.

I run git mesa/drm/nouveau.  Using kernel 2.6.25.  Using git xorg from a few
weeks ago.

Any help to debug this further would be nice.

Thanks,

Nick
