Could you try to play with different eventtimer settings (preferably in
current) ?
You can use this thread / PR as a guide:
http://thread.gmane.org/gmane.os.freebsd.devel.amd64/14480/focus=14495
The place where boot stop looks suspiciously close to the place where timer
interrupts should start driving the system.
Yes, that's it!
Setting kern.eventtimer.timer="i8254" let's the Thinkpad boot on
CURRENT with the AC cable inserted.
Please share your sysctl kern.eventtimer output with Alexander.
He will probably ask for some additional information :-)
Sorry if I've missed, but it would be useful to see verbose dmesg in
situation where system couldn't boot without switching eventtimer.
No problem. See: http://bsd-geek.de/FreeBSD/IMAG0190.jpg
No, I've seen that one and I don't mean it. I mean full verbose dmesg of
successful boot in conditions where system was not booting before
without setting kern.eventtimer.timer="i8254".
Ok, sorry.
Here's a verbose dmesg booting CURRENT without AC power:

Hmm. I see nothing suspicious. HPET driver output is typical for ICH8M
chipset, many of which are working fine in different systems, including
several mine. There was no significant changes in HPET after 9.0-RELASE
except r231161. It changed device probe order that increased chance of
interrupt sharing. It should not be a problem, but who knows. You can
try to hint HPET driver specific IRQ 23 (that looks unused) to avoid
sharing by setting hint.hpet.0.allowed_irqs="0x00800000".
You've told that problem related to AC power state. Have you compared
dmesg outputs with and without it?
