Boy, that looks familiar..
try shutting down the system and unplugging and replugging all of the
keyboard connections (both ends) and the mouse.
I struggled with a similar situation as you for 6 months. I tried
everything possible to debug the problem. A few times I even thought
I had fixed it but the crashes resumed shortly.
I tried:
1) boosting the power supply up a little
2) removing non-used loadable drivers
3) completely removing the mouse
4) re-arranging order of loadable drivers
5) reseating all of the socketed chips
6) blowing out dust-bunnies
7) many other minor suggestions from other unix-pc'ers
8) and now, unplugging & replugging in the keyboard at both ends while
the machine is shutdown.
And the strangest thing is, almost everyone of these changes led me to
believe that the problem was solved. For instance, when I unplugged the
mouse, my machine remained running for 7 days but then resumed the frequent
crashes. When I removed an un-used loadable driver the system stayed up
for 3-4 days before the crashes resumed. The funny thing is that after
everytime I though it was fixed, I posted an article telling everyone that
I had solved my problems. Then I had to followup and tell everyone that I
was wrong once again.
So, after 17 days of uptime, I am relunctant to post this because I will
probably just jinx myself again. Oh well, here it goes...
