@Kyle: wrt random kernel panics, I had them too on my P2020RDB and attributed
them to RAM errors.  Before they happen, the kernel already complains about
corrupt data in the logs and GCC randomly crashes when running a sufficiently
large parallel build.  After power-cycling the GCC crashes usually vanish, so
maybe there's a small chance that DDR RAM is slightly miscalibrated by u-boot? 
Reducing the DDR clock might help.
