If you verbose boot, do you see it attempting to probe (?) lots of scsi 
id's that don't exist?    I have an issue with a QLogic fiber channel 
card doing this on 6.0-B3 but not on the most recent 5.4-STABLE.   It's 
definitely something in CAM that isn't right.  If anyone wants more 
info, I'd be happy to provide it.

Anything that works is better than anything that doesn't.
