>Description:
I usually enable DIAGNOSTIC on at least some of my NetBSD machines to flush out any hiding gremlins. Well, looks like it worked again.

I took GENERIC, enabled DIAGNOSTIC and DDB_ONPANIC=1:

diff GENERIC GALADRIEL 
85c85
< #options      DDB_ONPANIC=1           # see also sysctl(7): `ddb.onpanic'
---
> options       DDB_ONPANIC=1           # see also sysctl(7): `ddb.onpanic'
103c103
< #options      DIAGNOSTIC      # extra kernel sanity checking
---
> options       DIAGNOSTIC      # extra kernel sanity checking


built the kernel and booted it. System rebooted mid-kernel-init with SIR (Software Initiated Reset).

Output from that:

>How-To-Repeat:
Take an Ultra-45 with NetBSD 10.1, install sources. Take the GENERIC
config, enable DIAGNOSTIC, build kernel and boot it. System resets.

I've also tried (just to verify) to build an unmodified GENERIC and boot
it instead and that worked just fine.

Unfortunately, the SIR straight up reset the machine, so I couldn't even
capture anything via DDB, all I have is the serial console output.

>Fix:
None.
