System: [ 1.0000000] NetBSD 11.0 (GENERIC) #0: Thu Jul 30 15:23:12 UTC 2026

Architecture: x86_64
Machine: amd64
>Description:
Trying to reboot with the GENERIC kernel on this particular
system causes what looks like a null pointer de-reference
in the kernel, ref. (Replacing some greater-then with colons
for the sake of GNATS):
