Xen users - Oct 2006 - Xen +suse 10.1 +ASUS A6iTc w/AMD Turion Dual Core processor

Hi

I have a new ASUS A6Tc laptop with 1.6 GHz AMD Turion dual core
processor. I get a strange error:

<4>0000:00:0b.0 OHCI: BIOS handoff failed (BIOS bug ?) 000007b4

<4>0000:00:0b.1 EHCI: BIOS handoff failed (BIOS bug ?) 01010001

This only occurs when booting into the xen kernel, not without xen.

Can someone tell me why and how it can be fixed?

Don''t know why, but those errors seem to be about USB devices
(OHCI/EHCI
are "Host Controllers" for USB IIRC). 

Not sure why Xen would make a difference, but try adding "nousb" to
the
Xen boot line - which of course could kill your keyboard if you''re
unlucky :-(

This is a notebook, so I use both external keyboard and mouse, so this
is not a good solutions.
