Anyone have any luck with this, if you're willing to try? 
I put Yosemite DP2 on a fresh partition (upgraded from DP1) and attempted to use FileVault to encrypt the partition. It doesn't seem to want to move past the "estimating" stage, been over 5 hours.
I've tried rebooting (as I've had to in Mavericks before), but to no avail.
