[PATCH] aacraid: fails to initialize after a kexec operation

[Salyzyn, Mark]

That is a failure to route the interrupts and is possibly an issue with
the kernel and the hardware, and not the driver directly (since there is
an expectation that request_irq will connect the interrupt to the
interrupt service routine). Judith reported success in the past with
this patch on her hardware, perhaps the motherboard on your system has
some odd BIOS setup of the hardware that is giving acpi or the apic some
headaches? Can you check out success or failure on other motherboards?
Please try the suggestions from the driver (safe flags)?

Sincerely -- Mark Salyzyn
