FileVault Stuck on Pause

I just got a new 13" rMBP with Yosemite installed. I chose to enable FileVault when I set the machine up.

Now, several days later, an app called "Reverting from FileVault" shows on the list of apps consuming a lot of energy.

I check FileVault in System Preferences, and it says "Encryption paused," followed by "Connect power adapter to resume encryption." Connecting the power adapter makes no difference, even though the machine recognizes that it's charging.

I've found several threads describing this problem, but no solutions.

• etc.

I've tried clearing the PRAM, going into Recovery Mode, repairing the disk and repairing permissions. Nothing has worked. I can't stop FileVault from Terminal, and when I try to enable it, it says it's already on:

$ fdesetup status
FileVault is On.
Encryption in progress: Pending

$ sudo fdesetup disable
Password:
Enter a password for '/':
...

$ fdesetup status
FileVault is On.
Encryption in progress: Pending

$ sudo fdesetup enable
Error: FileVault is already On.

Any suggestions? The machine is brand new, so there isn't a HUGE amount of data on it (nor are there any Time Machine backups), but I'd like to avoid having to wipe the drive.

If there's nothing I can do, does Apple have a history of issuing hotfixes for issues like this?

EDIT: FWIW, one of the threads has the following post:

Talked to Apple Support and they told me that it is a known issue and will be addressed in future updates or patch. Only thing you can do is wait for fix or reinstall OS X.
