>How-To-Repeat:
See above.
>Fix:
Unknown at this time, but the following files changed between those two date tags:
P sys/arch/x86/x86/via_padlock.c
P sys/crypto/aes/aes.h
P sys/crypto/aes/aes_impl.c
U sys/crypto/aes/aes_keysched.c
U sys/crypto/aes/aes_keysched.h
P sys/crypto/aes/files.aes
P sys/crypto/aes/arch/x86/aes_via.c
P sys/external/bsd/drm2/dist/drm/nouveau/nouveau_fence.c
The AES changes are the likely culprit, as I think they're involved in entropy harvesting, in which autoconfigurating timing is an input.

On top-of-tree, if I revert this commit[*]:
=
https://mail-index.netbsd.org/source-changes/2025/11/22/msg159124.html
then the kernel boots.
[*] Also reverting the things stacked on top of said commit, but =
that=E2=80=99s the commit that appeared in the problem date window.
