This causes an immediate and total lock-up of my CPU, so it does have
this CPU bug in it. It's a brand new AMD K6-266, so I guess they
didn't implement a new stepping on these 0.25 micron CPUs :^( They
said it would be fixed in the next stepping.

Mine just said "Unknown speed detected." It knew it was an AMD CPU,
but it couldn't figure out its speed. The little assembler source
has a data table in it that only goes up to 233MHz, so it couldn't
figure out my K6-266 running at 300MHz :^(

OK, I would still be really surprised if this CPU bug, which apparently
has existed since the original K6's, is causing your RH5.1 kernel crashes.
Please let us know what the problem turns out to be when you diagnose it.
