Intel SE7500WV2 not working with ACPI

This is the source of the problems.  When acpi0 fails to attach,
everything else is done through the legacy PCI code.  The question is, why
is it failing?  The above-mentioned EC method could indicate the problem
is in walking the namespace but we'll have to look at the ASL to be sure.

Please send a url to the output of:
     acpidump -t -d > brooks-Intel.asl

Also, build with options ACPI_DEBUG and set these in your loader.conf:

debug.acpi.layer="ACPI_ALL_COMPONENTS"
debug.acpi.level="ACPI_LV_OPREGION"
