It turned out that I have put a SanDisk 4GB microSD card in and planned to copy the images on the card to M1, but M1 seemed couldn't read the card, so it hung at "I: Booting from filesystem...". Now I ran "sudo ./reflash_m1.sh --snapshot milkymist-firmware-11282011-0543" again and took the card out, everything worked again.
One thing I found out is: 1. In M1 GUI, click on "Shutdown" button. Shutdown windows pops up. 2. In Shutdown window, click on "Shutdown" button, M1 rebooted instead of shutting down. 3. So I unplugged the power cable, replugged the power cable and M1 started fine. 4. I tried Shutdown again, and this time M1 didn't go back as it suppose to. 5. I plugged USB cable to Serial board, ran "cat /dev/ttyUSB0", then saw error messages "USB: HC: RX timeout error" 6. I unplugged and replugged power cable, M1 started fine again I don't know why the second time on, rebooting didn't work any more, I hope the error messages I got could give you a hind of the reason. 2nd, I think we do need to change the "Shutdown" text to "Reboot". Since my microSD card doesn't work on M1, I will need to find a way to copy images to M1.
