Comment 15 for bug 666828

Just re-loaded, lspci reports the affected controller as being the following:

07:01.0 RAID bus controller: Compaq Computer Corporation Smart Array 64xx (rev 01)
        Subsystem: Compaq Computer Corporation Smart Array 642
        Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 18
        Memory at fdff0000 (64-bit, non-prefetchable) [size=8K]
        I/O ports at 5000 [size=256]
        Memory at fdf80000 (64-bit, non-prefetchable) [size=256K]
        [virtual] Expansion ROM at 80300000 [disabled] [size=256K]
        Capabilities: [d0] Power Management version 2
        Capabilities: [dc] PCI-X non-bridge device
        Capabilities: [f0] Vital Product Data
        Kernel driver in use: cciss
        Kernel modules: cciss

During boot, I see in `dmesg`:
[ 1.097409] HP CISS Driver (v 3.6.26)
[ 1.098444] cciss 0000:07:01.0: PCI IRQ 50 -> rerouted to legacy IRQ 18
[ 1.098524] cciss 0000:07:01.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18
[ 1.098694] cciss 0000:07:01.0: Controller reports max supported commands of 0, an obvious lie. Using 16. Ensure that firmware is up to date.
[ 1.216111] cciss 0000:07:01.0: cciss0: <0x46> at PCI 0000:07:01.0 IRQ 18 using DAC

I'm not sure what the firmware update procedure is on these things.
