Hi Marc,

modprobe is not complaining with tegra-aes, but the timeout message is 
still apearing:
Error unlocking device: timeout (10s) waiting for cleartext device to 
show up

Nothing happens for the drive, a second click on the encpryted symbol 
starts another job (cryptsetup) consuming around 50% of total CPU time.

best regards

Andreas
