Boot failure on 4000/500A

[George Harvey <fr30%dial.pipex.com@localhost>]

Hi,

I have a VAX 4000/500A with a CQD-223/TM QBUS SCSI card. It was
previously running NetBSD 6.1.5 on an external SCSI disk and has
recently been upgraded to NetBSD 8.0. The 8.0 install kernel was
netbooted, found the SCSI disk (ra0) and completed the installation
normally. After rebooting, the generic kernel fails to find the CQD
card. Included below are the console outputs from the install and
generic kernels.

I remember some discussion a while back about boot problems with large
kernels on some hardware models, could that be the problem here? The
disk boot loader is:

  NetBSD/vax boot [1.12 (Tue Jul 17 14:59:51 UTC 2018)]

Thanks,
George
