acpi_cpu_idle panic (Was: Re: kernel panic with todays source)

[Nate Lawson]

The panic you see is a result of the new acpi_cpu driver, not ULE.  In any
case, it appears that acpi_cpu_idle is being called and trying to read one
of the processor control registers before they are present.  Please send
me privately the output of:
   acpidump -t -d > harald-MachineType.asl

As a workaround, please set this in loader.conf:
   debug.acpi.disable="cpu"

That will allow you to get running and give me some time to look into
this.

Thanks,
-Nate
