Subject: oops: 2.6.24.4 [tainted]

Hi

I have an old K6 200/430TX system (used for routing and backups) on
which I have been chasing random crashes and reboots for a while.
Normally there is nothing in the logs. They seem to happen under high
load, but are not reproducible reliably.

I have just replaced all the RAM with new, but still got this oops this
evening.

Unfortunately, the kernel is tainted by madwifi. I will change to ath5k
as soon as my card is supported :)

Could someone help me decode this. Is it real or faulty hardware? Let me
know if other info would be useful

Thanks,

Mark
