Re: CMD controller not found on 4000/500A



And I know I had problems finding controllers on an 8650 if I had too much memory. But I think that was more than 128M. But it could be related.

There were some things spotted/fixed for VAX in the kernel not long ago. How long ago was your kernel built?

128 MB, which is the same as the 705A that was showing similar symptoms in the linked thread.

Hi,

I have a 4000/500A with CMD CQD-223/TM SCSI controller. I did a network install of 10.0_RC3 onto a 4.3GB SCSI disk and it all proceeded normally until the reboot when the kernel failed to find the CMD controller. If I netboot the same kernel, it does find the CMD card and the system runs normally. I have since updated to the RC4 kernel and see the same behaviour. The relevant lines from kernel are:

Netbooting 10.0_RC4 GENERIC

Booting the same kernel from the SCSI disk (DUA1):

[   1.0000000] uba0 at mainbus0: Q22
[   1.0000000] mtc0 at uba0 csr 174500 vec 774 ipl 17
[   1.0000000] mscpbus0 at mtc0: version 4 model 14

[   1.0000000] qt0 at uba0 csr 174440 vec 770 ipl 17

The CMD card at mscpbus1 is missing when booted from disk.

Looking back through the mailing list archives, I see something similar reported for 9.3 on a 705A in this thread:

    http://mail-index.netbsd.org/port-vax/2023/02/01/msg004175.html

However, it doesn't look like a solution was found. Did anyone find a solution?
