This patch didn't fix the panic:

	http://people.freebsd.org/~pjd/misc/acpi_unplug_panic_1.jpg

In the meantime I found two other panics.

One is when I leave laptop idle for some time (few hours?):

	http://people.freebsd.org/~pjd/misc/acpi_idle_panic_1.jpg

And when is when I boot laptop without power connected and I connect the
power:

	http://people.freebsd.org/~pjd/misc/acpi_power_connect_panic_1.jpg

BTW. On the acpi_power_connect_panic_0.JPG photo, at the top of the
screen you can see error messages that are logged every second when I
have power disconnected. This is not a new problem. I had this problem
when I bought this laptop, but now that I'm reporting those bugs, I can
as well let you know about this one.

I'm running this on Thinkpad T530.

I understand that those problems are specific to my laptop and that on
your laptop all of the above work just fine?
