While you guys are at it, can someone fix this too pls (ASUS board with

That is actually a BIOS problem. I wonder whether it would help to turn this
into a WARN_ON to get the board vendors to release working BIOSes.
Opinions?
Good luck trying to get ASUS to fix anything in their BIOS :(.
I have tried to contact Asus in the past to have them fix the issue, but I got no luck. Once it is out in the field, it's very difficult to get them to make changes. I am also addressing this issue with the BIOS team for the future hardware.

Turning this into WARN_ON() at this point might break a lot of systems currently out in the field. However, users can always switching to use "intremap=off" but this might not be obvious.

Can't we detect the SB IOAPIC some other way in this case?
