[Gerd Zellweger]

Hi,

Just in case: If changing the bridge program as suggested by Stefan is 
not helping, you can also try this small patch that essentially disables 
the assertion.
AFAIK that bound check there, which is reported by ACPI seems to be (at 
least on our machines) not really a strict limit and can be ignored.
