When I was in XF86_SVGA playing quake 3 with the glx (OpenGL) XFree module
inserted I had this oops. Nothing was recorded in the kernel logs, I was
able to capture it over the serial console line. It looked like to me the
2nd oops was repeated with a longer stack trace over and over until the
machine (hung or rebooted I forget which).
The system is a K6-2, NRC53c810 scsi controller, Matrox G200 video card,
and gcc 2.95.2.
