Re: KERNEL_PANIC null memory on KM_SLEEP request

[Jeremy Jackson <jerj@xxxxxxxxxxxx>]

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
