There was more detail on IronForge's problem posted to
bugs@; a brief look at the trace output shows a failure to store AML code type 8; you may compare it to
this problem report on tech@ which fails to store AML code type 100. Both IronForge's report and the report on tech@ were using a -current kernel from the last week of March 2013.
The CVS log for the module containing aml_store --
sys/dev/acpi/dsdt.c -- has had
four patches since then which might resolve aml_store panics.
Unfortunately, all I know of AML is how to spell it and then
look it up in Wikipedia:

Hardware interface
ACPI-compliant systems interact with hardware through either a "Function Fixed Hardware (FFH) Interface", or a platform-independent hardware programming model which relies on platform-specific ACPI Machine Language (AML) provided by the original equipment manufacturer (OEM).
