Just got my X100e in the mail. Installed alpha3 from CD, this happens to me. Did full package upgrade as of 2010-03-12, it still happens. As long as AC power is plugged in and the laptop is actively used, it's fine. Removing AC power causes a hard lock. Not touching the machine for several minutes causes a hard lock (I didn't time it, but probably whatever the default screen power save timeout is). The only solution is a cold reset.
