Hi,

I recently bough a SAS/SATA expansion card[1] based on Marvell's
88SE9480 chip:

	$ lspci -nnv
	[...]
	04:00.0 RAID bus controller [0104]: Marvell Technology Group Ltd. Device [1b4b:9480] (rev 03)
		Subsystem: Marvell Technology Group Ltd. Device [1b4b:9480]
		Flags: bus master, fast devsel, latency 0, IRQ 7
		Memory at efac0000 (64-bit, non-prefetchable) [size=128K]
		Memory at efa80000 (64-bit, non-prefetchable) [size=256K]
		Expansion ROM at efaf0000 [disabled] [size=64K]
		Capabilities: <access denied>

	$ 

As you can see, the "mvsas" driver failed to get the card up and
running. That's because there is no matching pci id:

	$ /sbin/modinfo mvsas

The attached (trivial) patch fixes the issue for me:

		Expansion ROM at efaf0000 [disabled] [size=64K]
		Capabilities: <access denied>
		Kernel driver in use: mvsas

	$ 

If there are no problems, please include the patch in the next upload.

Best regards

Hi,

although the patch made my system recognize the HBA, there were several
severe issues when actually using it: I experienced random reboots
during POST and several freezes during heavy I/O. Additionally the
system always failed to wake up from S3 when the HBA was plugged in.

I'm therefore going to return the card in a few days. You may still
consider merging the patch since it made my system at least recognize
the HBA after all.

Best regards

Alexander Kurtz
