Hi,

I upgraded a FreeBSD box from 2.1.5 to 2.2.1, and am having a fair ammount
of trouble with my old ccd disks.  I had two disks, each on its own bus,
in a concatanated volume.. but now under 2.2.1, it no longer works and I
get SCSI timeouts.  The specific error is:

Mar 25 09:41:16 bob /kernel: ncr0: timeout ccb=f130cc00 (skip)

Below is the dmesg output of the machine:

Does anybody have any ideas on why this no longer works, and how I could
fix it?  Thanks..
