I also experienced this a week or two ago. In fact, I ended up hard-resetting my TP2 and restored with an SPB Backup. For different reasons, I got another refurb last week, and this briefly happened once as well. It stopped the boot just before the "Loading TF3D" message came up. But I gave it a while, it eventually loaded, and hasn't recurred since.

I would love to know what causes this...
