dmesg log

Hello,

I've just installed an old Radeon X600 card in my system but I get random Xorg
crash when I play video files using XVideo extension.

dmesg is filled with:
[  404.661224] [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule
IB(9).
[  404.661233] [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !
[  464.661166] [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule
IB(10).
[  464.661176] [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !

I've got 2 displays, the one I mainly use is connected through DVI connector
and the other is connected using VGA connector. When the crash happens, I get a
black screen on both display but I can switch back to console and the VGA
monitor is OK, while the DVI one is still black.

If it's of any help, I previously had a Radeon HD3450 and never got that kind
of problem (using the radeon driver also).

Best regards
