Summary: NULL pointer dereference -
radeon_unmap_vram_bos+0x22/0x50
Product: Drivers
Version: 2.5
Kernel Version: 2.6.35-rc3
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
AssignedTo: drivers_video-...@kernel-bugs.osdl.org
ReportedBy: bugz.kernel.tor...@xoxy.net
Regression: No
I was testing the game Lugaro on M26 (RV410), switching between different
resolutions in the game's options menu. The LCD native 1680x1050 made the game
cursor very slow, so I chose 1400x1050 (have to quit the game and reenter to
take effect). After that I could not go back to 1024x768 (default, works well),
only 1400++ resolutions were listed. Then suddenly X froze, but sysrq-B worked.
I am not sure if this is a recent regression, because it is the first time I
try out different resolutions in this game, and the issue might not be easy to
reproduce as it happened after a series of resolution switching.
