I think p4tcc is not the problem, it's the combination of the two. I think there are some problems when both the chipset (externally) and processor (internally) assert STOPCLOCK. If this works for you with no hangs, I'll commit code to disable acpi_throttle when p4tcc is present. p4tcc is more efficient than acpi_throttle since the latter is done through the chipset, giving more chance for race conditions, latency, etc. -- Nate _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
