Hello Andrew,

the ACPI bug or the problems with 2.6.13-rc3-mm[2,3] gone.
The system boots now noiseless, except on problem with USB.

If my Prolific USB-Serialadapter  plugged in on reboot
the ehci_hcd driver complains about a Hand-off bug in Bios.

-> snip

ehci_hcd 0000:00:1d.7: EHCI Host Controller

ehci_hcd 0000:00:1d.7: debug port 1

ehci_hcd 0000:00:1d.7: BIOS handoff failed (104, 01010001)

ehci_hcd 0000:00:1d.7: continuing after BIOS bug...

ehci_hcd 0000:00:1d.7: new USB bus registered, assigned bus number 1

ehci_hcd 0000:00:1d.7: irq 161, io mem 0xd2dffc00

-> snip


I wonder about this because all other USB devices working without this 
message on boot.

USB Mouse,Keyboard and USB Storage and all mixed from USB 1.1 and 2.

When I rebooted without plugged Prolific Adapter and plug them in the 
same port
the kernel prints this message.

->snip

usb 4-1: new full speed USB device using uhci_hcd and address 2

pl2303 4-1:1.0: PL-2303 converter detected

usb 4-1: PL-2303 converter now attached to ttyUSB0

-> snip


Any Ideas what could be wrong here?
