I've bisected the source and have determined that the fault was introduced
with:
/* $NetBSD: intr.c,v 1.163 2022/10/29 13:59:04 riastradh Exp $ */
Reverting this file to r1.162 eliminates the crash on my pentium-III
and Am5x86 (GENERIC kernel) systems.
It is not clear why the NET4501 kernel (or a kernel derived from it) does
not exhibit the crash. I thought it might be because these kernels never
enable "options DIAGNOSTIC", but disabling it in my GENERIC-derived kernel
did not avoid the crash.
I'll see what lineup of i386-class (i486 and 32-bit pentium) CPUs I can
manage and try to see where the "go/no-go" line is.

The "do the kernel first" is sort of a "general warning". Whether it is strictly needed depends on what version user-land and what version source you are trying to mix. Ultimately, if you e.g. install a -current libc and still run a 9.3 kernel, I predict that you are going to have a hard time recovering from the mistake. As for the build error, it's difficult to say. Building the kernel typically requires that it *not* be done against the (possibly old) headers of the running system, and possibly also with the compiler and tools in the "tools" build.sh result. It's difficult to know what failed in your case without significantly more details. Regards, - Håvard

How do you do the kernel first without building the userland to build the
updated tools?
I tried again to build for amd64 but failed on something with amdgpu.
*** Signal 11
Stop.
nbmake[7]: stopped in /BETA1/netbsd-HEAD/usr/src/sys/modules/amdgpu
*** Failed target: dependall
*** Failed command: cd "/BETA1/netbsd-HEAD/usr/src/sys/modules/amdgpu";
/BETA1/netbsd-HEAD/usr/src/../tooldir/bin/nbmake realall
*** Error code 1
I don't know what to do further regarding NetBSD update, except maybe try for
i386, where there seems to be no reference to amdgpu.
