There's no need to talk about the "missing" resume partition problem in this bug any longer. That issue needs to be spun off into a new bug of its own (and ideally a link to that bug posted within this one). This deals with 1. and 3.

I don't think the change in 2.6.20-16 affects ICH7 controllers - unlike the ICH5 the ICH7 I tested was still using ata_piix in 2.6.20-16 (i.e. ata_piix is only disabled for the ICH4/ICH5). Do we have any ICH6 sda -> hda "switchers"?

We need to find out what the link is between IRQ timeout sufferers. Are they only ICH5 owners? If so is there something else which links these suffers together but excludes others ICH5 owners? My BIOS idea was only speculation. Perhaps cat /proc/interrupts will show that the disk controller is being shared with another device?

Finally, Bug #117413 looks like a good focal point for discussing the /dev/sda problem for *only* CDROM drives (perhaps the /dev/cdrom symlinks should be used instead since CD drives don't have UUIDs)?
