It looks like your motherboard's DSDT is doing something hokey. I would
complain to the board manufacturer about this. For the timebeing, you can
dump the DSDT into ASL format, modify it, compile it back to DSDT and load
a proper version on system startup. If this is your first time, you
probably want to run "acpidump -d > my.asl" and make the resulting file
available somewhere.
Would you also mind sharing the kernel config file that was used to build
the kernel that gaves you the mother of all interrupt parties?
Cheers,
Andy
