1) Retry with "hw.acpi.auto_serialize_methods=0" in /boot/loader.conf
It helps, thank you. Errors gone. Where I can read about this tunable?
It's a new feature of ACPICA 20140214 and I thought it was safe to turn
on. See /ust/src/sys/contrib/dev/acpica/changes.txt, first paragraph in
the news about 20140214 ("Implemented a new mechanism..."). I also added a
line about it in the acpi(4) manual page. I think I will switch the
default to off for now until I understand the implications a bit better.
I'm still learning.
2) Check if the latest BIOS is installed
I think, Dell did not update BIOS for so old laptop. Anyway, I'll check
it later.
3) Put up the output of 'acpidump -b' somewhere (it will output a
number of *.dat files).
