Since then I got one or two hangs a day and entering
the debugger never worked out, even if my console connection
was opened a few minutes before the hang.

I no longer think it has anything to do with the terminal
server, but assume the hang takes the console with it.

sio0 is running on acpi0, so I tried to disable acpi
to see if it changes anything, but the only change I
got was that fxp0 stopped working (it is up but only
produces timeout warnings).

I tried to partly disable acpi subsystems like
described in acpi(4), but either I got the
syntax wrong, or it just isn't working.

Can someone on this list confirm or deny if
something like debug.acpi.disabled=isa in
/boot/loader.conf makes sense?

That's how I understand the man page, but I don't see any
reaction. I also tried /etc/sysctl.conf (which probably
is parsed too late anyway) but I just got a message that the
sysctl does not exists.

sysctl debug.acpi indeed only shows:
debug.acpi.do_powerstate: 1
debug.acpi.acpi_ca_version: 0x20041119
debug.acpi.semaphore_debug: 0

so maybe I need some special acpi options
or it just doesn't work if acpi is loaded as a module,
but as least the man page has no such hints.
