It was progressing earlier -
There was a message to the right and above the normal progress bar that read "FSCK 42%" - it was stuck on 42 for a while and I did a hard restart thinking it was stuck. Powered down, unplugged for a few seconds and powered back up.
This time, I waited through it - it eventually hit 100% then moved on to this "Initializing. Please wait" screen.
I have been here about an hour. Like I said, it is still twirling - and ever so often, the hour glass will stop for a few seconds, then proceed to twirling.
I would hard restart again - but fear that it would just start over - if, in fact, it is working its way through something.
I can't find any documentation on it anywhere.
