Although it originally sounded like a kernel problem, because it appeared contemporaneously with a kernel update, the bug report makes it sound more like an issue with os-prober. So that might explain the failure to recognize a btrfs fileystem (and the Linux OS on it) as well.

I'll do it first thing in the morning and report back.

Today I updated reinstalled GRUB2 with the GRUB2 editor ( http://kde-apps.org/content/show.php/GRUB2+Editor?content=139643 ) Now it all seemed to have come back. Disks was found again *knock on wood* so seems to be solved, atleast for me.
G2E I had installed priviously for the rescue ability it had. Feels there was some kind of conflict. Not sure. Just thought I'd say if anyone else get hit by this problem, since a Live Kubuntu USB didn't work, only with super GRUB disk.

I had a major problem with GRUB yesterday - moved 12.04 to the partition where 11.10 was residing, which is the primary boot system on the disk. Wouldn't boot, nohow. Had to use a SuperGrubDisk, and then go through the whole grub setup procedure, which didn't help. "sudo grub-install --recheck /dev/sda" is what finally fixed it.
For what it's worth, I never could get grub to boot with btrfs. Apparently the only way to do it is to use a separate non-btrfs partition with the grub files on it.
