I have the same problem too, again Ultra5/Mach64. Again, it happens randomly
and not nearly as frequently as the original report. The length of time X is
running seems to be a factor; certainly if I log out at the end of each day
(thus restarting X) it seems I am much less likely to run into trouble than if I
leave X running. However, I am pretty sure I have seen it happen with 2.4.1.
Generall speaking, it hits monthly. I have problems with X crashing on a more
The symptoms are that the entire display, X *and* console is scrambled. The
cursor becomes an white square and otherwise as has been said it looks like
sync has been lost. It looks very much like some incorrect value has been
written into a Mach64 register which is not otherwise touched by the frame
buffer or X code. Certainly stopping and restarting X does not cure the
problem; a reboot is the only answer.

My modeline (which I think is a standard Debian one) is:
ModeLine "1280x1024x76" 135.0 1280 1312 1376 1664 1024 1026 1034 1066 -hsync -
Depth is 16. FWIW, monitor is a Ilyama Vision Master 17.
