Again, new to my CAM kernel, the following error:

Either the NCR or someone else on the bus reset the bus, but the proper
asynchronous notification was never sent to the CAM transport layer so
that the da device could expect to receive a UA. So, the driver erred
on the safe side and invalidated the device. The only way to be able
to access it again is to do a "umount -f" and then remount the partition.
I took a quick look at the ncr driver, and it look like the NCR driver will
have this effect if it encouters a "fatal error". It looks like the call
to xpt_async should be moded to ncr_init.
