I've got several oops (>20) in a period of 4 hours (until someone reset the
machine).
They are all the same except for the process involved:

Could this be a hardware problem? I was told the machine was a bit unstable
with
problems also happening with the previously 2.0.36 kernel.

This is a PP200, SCSI (aic7xx driver), 128 MB, ethernet 3c590 Vortex and the
kernel is linux-2.2.12up from Redhat 6.1.

Thanks for any help,

Rui Sousa
