>Description:
Attempting to boot NetBSD kernel as of a recent HEAD
snapshot [1] via Syslinux mboot.c32 module under Qemu 3.1
from Debian 10 (oldstable) results in a panic, apparently
due to the CPU being misidentified as 80386-class:

This looks like a regression, as NetBSD 9 kernels I?ve used
so far (9.1, 9.2, recent snapshot [2]) booted correctly in
such a configuration.
[2] http://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-9/202207180150Z/source/sets/syssrc.tgz
A cursory glance at the diffs between the respective revisions
of usr/src/sys/arch/x86/x86/identcpu.c and cpu.c, as well as
usr/src/sys/arch/x86/include/cpufunc.h didn?t reveal anything
that might?ve been responsible. However, there seem to be
much new code in usr/src/sys/arch/i386/i386/locore.S (where
cputype and cpuid_level are initialized) related to Multiboot,
so that seems like a good starting point to look for the cause.
(JFTR, I don?t have a NetBSD system at hand right now, so
I cannot try booting with NetBSD?s own /boot to check whether
the issue is specific to mboot.c32 /or/ Qemu. Though unless
someone beats me to it, I?ll probably try that within a week
or two.)
>How-To-Repeat:
I?m going to use GNU Mtools, Syslinux and Qemu from Debian 10,
but the same should be available from pkgsrc. The truncate(1)
command that I?ll use to create a sparse file of the given
size doesn?t seem to be ported to NetBSD yet, though. The {,}
and ${var^^} expansions below are specific to Bash.
We create a sparse ?hard disk image? file; create an MBR
partition there; initialize Ecma 107 filesystem; copy the
two kernels to test there; put Syslinux MBR code into
the first 440 bytes of the image; install Syslinux core;
copy a selection of Syslinux modules; copy Syslinux
configuration; boot Qemu twice, once for NetBSD HEAD kernel
(misnamed NetBSD 10 below), once for NetBSD 9 one.
