533	Poor performance, trap e and no power off on Intel 945C SBC	BlondeGuy	David Azarewicz	"I'm working with an single board computer in a passive backplane industrial computer. Intel 945C-based system. Works without ACPI, but does not power off. Works with ACPI 3.18, but does not power off and did not attempt /SMP. CPU is single core hyperthreading CPU.

ACPI 3.19.15 booted OK first time, but no power off. Second time, I got the situation (which every version of ACPI has always done occasionally on every machine I've ever tried.) with high CPU use. I didn't try this time, but CPUSPEED usually will show both CPU running at radically different speeds.

I tried to power off, and I got trap E. See attachment for register dump screen."	defect	closed	major	Feedback pending	ACPI PSD	3.19.15	unknown
