This is blowing up on graphics side, not obviously related to bt

Normally there's not much idea to be had from that, but yesterday we
found a problem with one of the Androidization patches that causes
crashes when under memory pressure.  It's an mm subsystem locking race
related problem giving pernicious results.

If you try again with a kernel from tilt-3.4
b71a84254eca700ad8cdf3e3735488cde746f2ac or later, it'll be interesting
to see if the problem is still coming.
