Bug 35965

This is the first time I recall getting a hard freeze on this relatively
old, and tested card.

seawolf XFree86-4.0.3-5

In the middle of typing, the display stopped responding.  xclock no longer
updated.  The pointer continued to follow the mouse.  No response to mouse
buttons.  No response to keyboard activity.

No response to CTRL-ALT-F[17], could not switch terminals.

I was able to succesfully ssh to this machine over the network, and
determine that the system was running just fine.  There was no load, the X
process was idling, strace showed X in a middle of a select(), idling.

I as able to easily kill X.  gdm restarted it, and I was able to log back
in, and resume working.  CTRL-ALT-F[17] worked again.

Too lake now, I forgot to check if X was receiving any input.

Asus P2B-DS motherboard, dual PII-400, 256MB RAM, 520MB swap.
