Comment 82 for bug 699802

Got the same problem, but not after installing Ubuntu or the ATI-driver. After a kernel update to, I think, I had the error message once, then a week nothing and since then I have this error message all the time, directly before the old 'Sparse file not allowed'-btrfs-related error. Now, both of them are terminal style, white on black, then the splash screen with big and ugly 'ubuntu-mono' like 'Ubuntu' letters (BTW the same on shutdown with overlaid shutdown messages.).
One error message on startup was more than enough, don't need two!
