I don't see this. specifically, there were scattered reports
of a via-ide problem a few months ago; this is the issue that's
gotten some press, and for which Alan has a fix. and there are reports
of via-smp problems at boot (which go away with noapic). I see no reports
of the kind of general instability you're talking about. and all the
via-users I've heard of have no such stability problems -
me included (kt133/duron).

the only general issue is that kx133 systems seem to be difficult
to configure for stability. ugly things like tweaking Vio.
there's no implication that has anything to do with Linux, though.

how many dimms do you have? interleave settings? Vio jumper?
already checked on cooling issues? and that you're not overclocking...

sure it does: (from my kt133 hostbridge)
