Occasinally, when exiting q3demo or changing video modes, X will hang
I haven't seen any particular pattern to when this happens, but when it
does happen, the mouse cursor is shown in the far upper left corner, and
both the pointer and crosshair are present. X doesn't respond, but
SysRq does. Therefore, I have the attached output from SysRq+S.
This problem happened with XFree86 4.1.0 and kernel 2.4.5-ac2, however
it has happened under several different combinations of X and kernels.
I can't recall a recent combination that worked. Some that haven't
worked have been tdfx-0.7 and a recent DRI CVS version.
In fact, I have output from kdb when a lockup occurred with tdfx-0.7.
This is the only other debugging info I have. It is also attached.
If there's any other information I can provide, or help debug in some
way, let me know. I read dri-devel in digest.
