Comment 0 for bug 788238

I have 2 Systems updated to 11.04 my workstation(64bit) und my laptop(32bit). The workstation has a sata-ssd disk with btrfs.
Now wen I boot the workstation I get the BusyBox from the initramdisk with a stacktrace and many mount errors. I put the ssd with a usb-to-sata adapter (Digitus) on my laptop and get the same dump only over usb. I red the bug 732149 and the info about rootflags=subvol=@ but the does not help :-(
