Based on your boot info you're using mps, so this could be related to
mps fix committed to stable/11 today by ken@
https://svnweb.freebsd.org/changeset/base/321415
re@ cc'ed as this could cause hangs for others too on 11.1-RELEASE if
this is the case.

Thanks! Tried it, and the message (or a backtrace) does not show
during a boot of a generic (patched) kernel, at least not in
the last 40-lines screen before the hang occurs.
(It also does not show during a "Safe mode" successful boot.)
Btw (may or may not be relevant): after the above experiment
I have rebooted the machine in "Safe mode" (generic kernel,
EARLY_AP_STARTUP enabled by default) - and spent some time
doing non-intensive interactive work on this host (web browsing,
editor, shell, all under KDE) - and after about an hour the
machine froze: clock display not updating, keyboard unresponsive,
console virtual terminals inaccessible) - so had to reboot.
According to fans speed the machine was idle.
The /var/log/messages does not show anything of interest
before the freeze. All disks are under ZFS.
Can EARLY_AP_STARTUP have an effect also _after_ booting?
This host never hung during normal work when EARLY_AP_STARTUP
was disabled (or with 11.0 and earlier).
