Log xorg with the error in the end after changing resolution in openarena

Hi,

I have an XPress 200M and I have switched to mesa git. I got a terrific speed
improvement (fglrx came from 400 to 1200fps).
But, I would like to report about a bug in both the radeon-rewrite and the
master branch. When changing the resolution in game (open arena for example,
but the problem is the same with other games), my system just locks or seems to
be stuck.

I already talked about this problem on
phoronix(http://phoronix.com/forums/member.php?u=8184).

Since then, I've finally got an error in the Xorg log :
(II) RADEON(0): [drm] removed 1 reserved context for kernel
(II) RADEON(0): [drm] unmapping 8192 bytes of SAREA 0xf8b53000 at 0xb7a21000
(II) RADEON(0): [drm] Closed DRM master.

I would like to add that using xf86-video-ati 6.12 and mesa 7.4.2 solves the
problem.

Hope this will help ! You're doing a terrific job ;)
