Hi,
As promised, I post the details of that strange error I experience during
shutdown. However, since I am now extremely tired, and apart from that,
extremely lazy, I had only enough energy to make some photos of the call
trace, which I placed here: http://hell.org.pl/~sziwan/calltrace1.jpg and
calltrace2.jpg. Please excuse me for that, if you find it uncomfortable, I
will type it in after a couple of hours sleep. :/

Anyway, what I do is start a 2.5.61 kernel (with ACPI compiled in and that
little fix you wrote), then immediately trigger shutdown -r now by pressing
ctrl+alt+del just when the gettys appear. No ACPI-specific operations are
performed. The shutdown scripts go just as far as here:
if [ -d /var/lock/subsys ]; then
  rm -f /var/lock/subsys/*
fi
and then the kernel dumps the call trace (before the next command). The
system reboots after that and so far no integrity loss has been observed.
Best regards,
