FW: Funny kernel antics
Good to know someone else saw the problem...I thought I was going crazy! :-)
I will try a lower version of the kernel...
I managed to get this from the logs: (don't know if this helps anyone to see the problem :)

---------------------------------
> Anyone know what causes this or seen this happen before?
I have no idea why but I did have this happen to me running 2.2.19.
Same exact symptoms.
Only thing unusual was that I had patched the kernel to support an
AACraid controller and made some modifications to run Oracle. At the
time I was using 2.2.19 on 5 or 6 other boxen without problems.
I was rushed for a solution, so I simply fell back to an older kernel
without investigation. I'm sure this was completely un-helpful.
