Hi Marcos,

Great news! I did not  find any solution to the issue. I have a REV C board
from element14. Is this the same board you are using?  In my board I saw
the issue.

Does this have anything to do with the patch you submitted [PATCH]
Beaglebone: fix missing clobber in inline assembly.
I have not yet tested with this patch.

The freebsd driver is working with cache disabled.  If possible pls check
if it is working with cache enabled in your board.
