Bjorn is using different SOC and board than the IFC6410 Am testing on, 
so its completely different setup.
on IFC6410 we did lot of stress testing and no issues seen. so 
suspecting the issues are very specific to that board or the eMMC Bjorn 
is using.

We are suspecting that the CRC issues are due to the fact that there is 
no code to manage regulators. My test setup uses dummy regulator, and 
the eMMC and external SD cards seems to be Ok with default voltages.

Am not sure if thats the same with Bjorn's board.

Thanks,
srini
