With the latest official firmware (and IO FPGA) from the VE CD 3.0: https://silver.arm.com/browse/VE030 MMC with the default card clock of ~500kHz is rock-solid :-) Personally I actually use it with mmci.fmax=12000000, which makes it rather fast. The downside is that I can't use any USB devices at the same time (well, you can do some tricks with IRQ core affinity to make it work). So 6000000 (6MHz) is a safe compromise. > I have just copied my 11.08 image to MMC and tried booting off that.

With the increased MMC card clock it becomes really usable, but then you may face an issue with the Ethernet ;-) https://bugs.launchpad.net/linux-linaro/+bug/673820 Which can be fixed with even newer IO FPGA files, as mentioned in the bug log.
