Our emails crossed, and I would like to warn people that I experienced some
questionable results with just be20def applied, after my machine got a
corruption of the mmc "EXT4-fs (mmcblk0p2): group descriptors corrupted!" which
stops the machine from booting. I have never had this before, and the
kernel I am using is the head of arm-3.0-ramp with just this one
mcam-core.c patch applied.
Other than the corruption the crash still happens for me on two machines.
