When running natty from a raid1 on a notebook (a small mlc ssd and one partition of a normal hdd) the normal boots takes over 1 minute. fsck and ureadahead take most of the time. When both are disabled (setting 0 EOL in fstab and removing ureadahead) the time for boot is 18 seconds. It looks like ureadahead is reading from one disk only - maybe this is an additional bug.

I consider this a bug because fsck.btrfs shouldn't take more than 20 seconds to basically do nothing. Isn't btrfs supposed to run without fsck anyway?
