acd0: FAILURE - MODE_SENSE_BIG timed out

[sam sirlin]

I've been getting these timeouts for some time on boot,  but up till now 
when they appear they just slow the boot down. After cvsup on 4/2, I now 
sometimes get a couple of new messages which hang up the boot process:
...
acd0: FAILURE - MODE_SENSE_BIG timed out
acd0: FAILURE - ATAPI_Identity ...
acd0: timeout state=0 unexpected
(hangs here till  hard reboot)

Are there some tweaks to parameters to prevent this?
