Thanks Thomas.
Your patch seems to fix a random hang during crypto operations.

Unfortunately it seems to hit the crypto performance too.
The command "cryptsetup benchmark --cipher aes-cbc"
gives me around 35 MiB/s instead of 50 MiB/s.

The patch did not fix the hanging which appears instantly after enabling tdma
in the driver and running some crypto operation.

Thanks,

Jussi
