Hi everyone,
We are having some randoms oops under high load! We think
it's related with aic7xxx drivers but sometimes the oops happen
without aic7xxx drivers loaded. Could be a VM issue either.
The oops happens frequently when we running by raid5/1 (raid-tools).
If raid isn't running the oopses gets more time to happen
(but happen, ~ one time a week). AND If aic7xxx isn't used
the oopses get more time to happen than when aic7xxx is used.
Generally some processes like mc, mcedit, find are the cause of
the oops. It's stranger. Follow the oops log:
