I'm having the same problem too (booting an IDE disk, but the separate SATA disk is complaining, same as comment 8 above https://bugs.launchpad.net/ubuntu/+source/linux- source-2.6.20/+bug/78288/comments/8 .
No issues previous from Warty through Edgy -- kernel 2.6.20-9 doesn't boot with sata-hd https://launchpad.net/bugs/78288 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
