Note the ^1, which flips the low-order bit. I commented this ^1 out on 2.4.19 and everything works as it should. The error was consistent with an incorrect flipping of the low-order bit. I have no idea why this change would have been put into place, or if it was even tested.
I do know some geode BIOSes have screwed-up IRQ tables in flash, so maybe they were fixing a problem but doing it the wrong way. Not sure.
I know we have some Linux kernel guys on the list, forward to whoever needs to see this if you wish.
I think Alan Cox added this because all of his MediaGX/Geode boards have a buggered BIOS.
You'd better tell him that he's wrong. :-)
