Not really, no... here's my configuration:

bha0 at pci0 dev 12 function 0: BusLogic 9xxC SCSI
bha0: interrupting at irq 11
bha0: model BT-958, firmware 5.05R

dracul (thorpej) ~ 174% ccdconfig -g
ccd0            64      0       /dev/sd0a /dev/sd1a

I keep several source trees on the ccd, which are accessed by 5 or 6
clients almost constantly, and the server itself does quite a bit
of building.  Objects are kept on sd2.  Basically, this machine is
my build server.

What sort of activity is going on when you see the timeout problem?
