I've had mixed results. When the box completes the boot the basic systems seem to work ok (I can get an IP and poke the filesystem). It still takes several minutes to get to a prompt as mentioned on the wiki page.
It happens quite often that the box does not get to a prompt at all. It fails to read the MMC properly. Below is two separate cases where reading the partition table fails. In the first case it finds one partition and in the second case it fails to find any partitions. The boot monitor has no problem reading uboot, kernel or initrd from the MMC when writing to internal FLASH.
I've also tried a different SD card with similar results. Sometimes it works fine and other times it reports I/O errors. I've tried the daily builds for 6, 8 and 10 October. Is this a known issue?
I can't fix your problem but for extra brownie points you could register this in launchpad as a bug and we can push for the right people to investigate.
Please file a bug at:
http://bugs.launchpad.net/linux-linaro
(sounds like a kernel related issue) and we will take it from there :)
We've already opened a bug on this issue:
