On i386, the ZFS-only installation reproducible works after the
first reboot but after the first reboot panics while importing
the root pool.

The problem seems to be that the GENERIC kernel is build with
clang but KSTACK_PAGES has not been adjusted according to UPDATING:

If the issue can't be addressed before the release it may be
worth mentioning it in the release notes.
