I'm using an AMD-K6-200. I've used kernels 2.0.30 and up on this
machine. If I'm not in X I never have trouble. With RedHat 5.0
this problem did not exist. The only relevant difference I see

1) New X windows with RedHat 5.1
2) New C compiler with RH 5.1

My AMD 486/66 was experiencing the same trouble, I've now
completely reinstalled RedHat 5.0 on it (instead of 5.1), I'm
using the supplied programs + KDE. Works fine. No lockups yet,
and I've done some nasty crash testing.

I'm almost positive it is a problem with X now.

Can you send me a URL for it?
