Hi,

Currently if you install the PowerVR SGX driver at a Pandaboard 4430
you'll easily find a kernel freeze while starting lightdm. That's due
a wrong revision check and an old implementation of errata 727915.

Both patches are already part of the latest tilt-3.2 kernel tree from
the Linaro TI Landing Team, and I tested and validated that it fix the
issue.
