Yes I'm having the exact warning with my system too. I already reported
this 2-3 days ago and
Borislav Petkov said that the backtrace was intentional:

"

For the reasoning behind why you get a backtrace instead of simple
warning see

"

I'd really like to know if that warning/firmware bug is leaving the kernel in an inconsistent state
because my keyboard also doesn't work if I don't give acpi=off during the boot.

I never upgraded my BIOS and I wonder why my keyboard is broken after a normal booting sequence.
The system was charmly working with 2.6.29_rc8, didn't have time to try 2.6.29{.1}.

Any helpful comment will be appreciated.
