Description Chris Rankin 2013-07-11 23:14:30 UTC 
WoW has started crashing with my Hd6450. A "git bisect" pinpoints this commit:

862f69fbe1e54e0e9a3c439450a14f0319648b60 is the first bad commit

    r600g: don't call buffer_wait in buffer_mmap_sync_with_rings
    
    The winsys should do this, because it measures how much time we spend
    in buffer_map doing synchronization, which can be viewed with the gallium
    HUD.

WoW's own crash dump analysis is attached, but the relevant part appears to be:

(It turns out that I was running WoW in DXD9 mode rather than OpenGL mode, but it still shouldn't have crashed.)
