Comment 20 for bug 770600

I just upgraded to Natty... and my root is on a pdc RAID. After rebooting, all I got was the initramfs BusyBox prompt with nary an error message or a single hint what was wrong. However, a quick glance in /dev/mapper revealed the problem. I managed to chroot in from an older version, add Phillip's PPA to my source list, and upgrade dmraid. Rebooted and everything works. THANK YOU--you just saved my ass. If I can assist with further information, testing, etc. please let me know.
