Your problem is likely because you have on board USB enabled......Via's usb implementation is quite faulty. Solution: Get a Pci usb adapter, turn off via on board usb and your difficulties will disappear."
From another post: "According to MS thishappens when you have a BIOS which is not 100% ACPI compliant. Obtain the latest firmware for your motherboard."

I had disabled USB Controller in CMOS Setup, but that didn't help. Again that message is available in the logs. My configuration is PIII 800 MHz, 128 MB SDRAM, Intel 815e Chipset, Board JETway 618AF. No more BIOS updates are available on the JETway's website.
