The other day my neighborhood remained in the dark for a 2 hour for blackout.
My raspberry when energy is returned has made several attempts to restart idle,
then work again "apparently" on a regular mode.
In earlier (many and many) times when it was switched off by disconnecting the
power, however, it was always started with a normal boot.

Today another blackout caused a restart with a dozen empty attempts.

What may have happened?

Raspberry-pi model B
Raspbian wheezy with all update.

... Sorry for google traslate!
