Does just the md5sum/dd hang or the whole system?  If you can, run ps and see
what state is the dd and/or md5sum in.  If it's in "D" state try 

# echo w > /proc/sysrq-trigger

and see what shows up in dmesg.  This dumps processes in wait state.

Otherwise

# echo t > /proc/sysrq-trigger

will dump all processes.

give that a shot & attach the resulting dmesg.

Thanks,
-Eric
