I agree, but recently I also expierienced very strange
stability issues with inadequate chipset cooling on AMD
systems, and missing PS/2 mices *smile* so it could be
anything ...
how to test?:
- memory: usually memtest86
- cpu: 1day kernel kompiling (on SMP with -jN)
- chipset/etc cooling (get a hairdryer ;)
if it is one system, simply replace motherboard
(with different type/cpu) and memory and see
if it is stable (usually the simples and fastest
way to stabilize) then, if you want to, hut the
issue down ...
best,
Herbert
