A GPE is an interrupt of sorts. I'm looking for any bad behavior the patch might cause. I'm certain it fixes lockups some HPs had during thermal zone events (i.e. fan switching on when it gets hot). Pretty much anyone with a laptop that locks up and you suspect acpi should test it. And anyone who is willing to test it on another brand laptop to be sure the patch doesn't break anything more would be welcome. You should be able to do "sysctl hw.acpi" and see the temperature and "apm" to see battery status without any new problems after applying the patch. -Nate
