Confirming this is still an issue in Maverick beta - it's worse than
ever. In lucid I had this error occasionally - since moving to maverick
it takes two or three failed boots (dumping down to busybox as grub
couldn't find the disk) plus lots of keypresses during boot to get it
going - it's like the interrupts from the keypresses kick it into life
again.
Once it's booted it's generally ok with errors and 30 sec system hang
only occurring every hour or so.
