Comment 4 Dave Jones 2006-02-12 17:55:06 UTC

I think this is related to ACPI changes to how _PSS objects are handled.
Reassigning for now.

Comment 5 Thomas Renninger 2006-02-22 22:24:05 UTC

Did you boot with acpi=off? 
Full dmesg would be helpful. Better try more recent kernel (best 2.6.16-rc2 or 
higher, a lot ACPI changes came in there).

Can you try recent kernels and make sure if the problem still exists?

Comment 15 Adrian Bunk 2007-02-24 09:11:55 UTC

Please reopen this bug if it's still present with kernel 2.6.20.
