Hi

Just another update on this stuff. I noticed that there has been a patch added* 
with spinlocks to the imx.c serial driver. I reverted this patch and now my 
serialfuz programm "only" kills the serial port with a not so nice oom 
condition. But at least it does not show the runaway interrupt problem.

Best regards
Tim
