Those Dell Perc4 controllers can be touchy. use an newer kernel, make
sure you have current firmware, and possibly patch your new kernel with
the latest perc driver, it probably has fixes not in the main kernel.
You should be subscribed to dell's perc mailing list, and check the list
archives, they probably have more detailed info.
Cheers,
Jeremy

I have a Dell 2650 with 4 Drawers of disks connected using two Perc 4DC
raid cards.
I'm running 2.4.20-19.9.XFS1.3.0smp. The server has two cpu's and 2GB of
memory.
Yesterday the server kernel panic with a :
KERNEL_PANIC null memory on KM_SLEEP request
The memory usage for the machine looks "normal" around the time the
system crashed.
There was hardly any swap going on.
Any ideas?
