Thanks Mark,

I applied this patch but it still does not work. Now oops is gone but
I get following while aacraid is trying to initialize.

Adaptec aacraid driver (1.1-5[2437]-mh4)
ACPI: PCI Interrupt 0000:01:02.0[A] -> GSI 25 (level, low) -> IRQ 25
aacraid: aac_fib_send: first asynchronous command timed out.
Usually a result of a PCI interrupt routing problem;
update mother board BIOS or consider utilizing one of
the SAFE mode kernel options (acpi, apic etc)
aac_fib_free, XferState != 0, fibptr = 0xffff810104140000, XferState = 0x810ad
ACPI: PCI interrupt for device 0000:01:02.0 disabled
aacraid: probe of 0000:01:02.0 failed with error -110

Thanks
Vivek
