ACPI panic

[Andriy Gapon]

Stefan,

long time, no news...

So, I decided to attempt a different approach to the problem.
Could you please try the following patch if you are still experiencing the
problem?  Could you please report how it goes?

My hope is that, even if the problem persist, it will be easier to debug it
using FreeBSD built-in debugging capabilities like INVARIANTS, WITNESS,
DEBUG_MEMGUARD, etc.
