56	ACPI, Asus P4C800 Deluxe	David McKenna	pasha	"  Using eCS 2.0 rc2 with ACPI 3.02 (debug), APM 1.17 and DaniS506 1.8.1.

  Motherboard is an Asus P4C800 Deluxe containing a 3GHz P4 CPU, Intel 875P chipset, ATI Radeon 9600 AGP video, 3COM gigabit NIC, ICH5/AD 1985 audio (see pci.log).

  With w4 kernal everything works good. With smp kernal and no switches or /SMP switch everything also works good. Problems occur when /APIC switch is added.

  With CPU set to no hyperthreading (and /SMP /APIC) the computer hangs during boot after all devices are loaded (see file Acpi-Hang-NoHyp.jpg). I need to do a hard reset.

  With CPU set with hyperthreading, /SMP /APIC boots and IRQ's are loaded high (see acpi-apic-hyp.log). The only problem is every 3rd boot or so, the CPU meter shows both are at 100% and IRQ load is ~20% and the computer runs very slow (see acpi-apic-hyp-slow.log). The floppy drive light also remains on all the time."	defect	closed	minor		ACPI PSD	3.02	fixed
