Description cjh 2003-05-25 08:00:31 UTC 
When large and long transfering between ahd device, it hangs with the
following message:

(da1:ahd1:0:3:0): SCB 0x34 - timed out

Fix: 

I don't know how to fix. As a workaround, I disabled tagged queueing
(found somewhere in freebsd-scsi mailing list) and copying can be done.

# camcontrol negotiate da0 negotiate -T disabled
# camcontrol negotiate da1 negotiate -T disabled
How-To-Repeat: 
/home -> 30G partition in da0
/home2 -> 30G partition in da1

cp -r /home /home2
(or tar, rsync, etc...)

Is this still a problem on 4.10?
