You could also attack the problem with the 2.6.22 kernel. AFAIK the bug
is not in the MMC driver, but the MMC core. A small change seems to
correct the problem for AVR32.

See this thread for patch and information:


Also, if your kernel is just booting too fast for the MMC layer to
detect the partitions, adding "rootwait=1" to the bootargs in u-boot
will let the kernel wait for the root partition to pop up.

With kind regards,
