I have been working to restore my uVax III system and the hardware seems 
to be working well. I have tested the hardware with VMS, copying 
hundreds of meg back and forth between my disks without error. My 
configuration includes two MSCP controlers, Emulex QD21 with one 800Meg 
ESDI disk, and the second a CMD CQD-220A/M/T SCSI that I can attach many 
different drives that include hard disks, CDROM, and MO drives.

I created a CD of the Netbsd 3.1 vax iso image and it boots ok (see boot 
log below.)
The install starts ok, but the MSCP device driver seems to hang at 
different spots during the install. If the partitions are large then it 
may hang during the newfs, but most often it fails when copying the 
files to the disk around 10 or 20 percent.

With one attempt where the source was a SCSI CD, and the destination was 
the QD21 ESDI disk, I have been able to ^Z the install and at the prompt 
can list files on the mounted CD. Any command that attempts to access 
the destination disk will freeze in a device wait state forever.

Another test with the source as a SCSI CD and the destination was a SCSI 
disk failed in the same way. The progress bar would stop at 10% or so, 
"- stalled -", and the KB/s would just drop. I could ^Z the install and 
list with ls files on the /mnt2 - CDROM, but when I tried to list files 
on /targetroot the ls would just hang.

I am willing to do more testing/troubleshooting if anyone has suggestions.

Thanks

Todd
