Dell Precision m4400 acline problems

[Stefan Farfeleder]

Hello,

I'm running FreeBSD current on a Dell Precision m4400 notebook and got
the following issue: When I unplug the notebook's power, the CPU
performance goes down to < 50%. While this isn't nice, the real problem
is that when I replug the power adapter, the performance stays low. So I
basically have to reboot to get back at full performance :(

I suspect this is an ACPI-related problem.  You can find dmesg output,
ACPI tables and ASL at http://people.freebsd.org/~stefanf/m4400/ .

BTW I'm not using powerd.

Cheers,
Stefan
