I also had this problem with the Windows port on my K6-2 
450.  After I reclocked the CPU to 400mhz, the problem 
went away.  (I find that AMD chips are frequently shaky 
at their promoted clock speeds, and only perform 
consistantly under ideal conditions.)
You may also wish to under-clock your CPU, which usually 
requires changing motherboard jumpers.  There are 
hundreds of web sites about overclocking - you can 
follow those instructions, but change the multiplier to 
be lower instead of higher (450->400: you would change 
from 4.5x to 4x).
