I can't comment on the LBA addressing issue, but if we can isolate the partmap detection one, then at least we can "fix" [1] this (which is what affects the majority of users). [1] With a kludge that loads "pc gpt" when partmap cannot be detected. Not sure if this is suitable for official grub, but at least we would enable it in Debian. -- Robert Millan My spam trap is honeypot@aybabtu.com.
