I get repeated panics on my notebook after recent ACPI update. The often
happen after ACPI writes about change in temperature.
ACPI DSDT on the notebook is known bad - I had to manualy "fix" it to be
able to start it. I'm sure there still are some bugs.
I can't get crash dumps for some reason. Should I be able to invoke dump
manualy from DDB? Often I get one after typing panic in DDB but often
is doesn't work.
