I have a very similar problem when I load drivers at the boot prompt (or
did you mean "root"?)

If you look at your dmesg (verbose not needed). I suspect that you will
se that there is no interrupt assigned to psm. If you are loading them
before the probe, try booting with ACPI and boot to single user (boot
-s). Hit Enter to get a shell prompt and load the needed modules
(kldload). Then exit to move to multi-user. I bet everything works.

I found that my system fails to assign an interrupt to psm if I have the
module loaded before I probe I/O devices.

jhb suggested an approach to fixing this, but I have not gotten around
to trying it.
