I've heard that due to bugs all high bandwidth devices are flakey.
Specifically, MMC and SATA media are unreliable and the best solution is
to try USB.
I have just copied my 11.08 image to MMC and tried booting off that. I
found that it does seem to hang but after 5 minutes or so it eventually
gets to the command prompt. Once booted, using ssh to copy a large file
gave a transfer rate of about 30kB/s.
It's a bit odd though if you find a 11.07 image works and an 11.08 image
does on the same kernel and MMC card.
