Thank you for reporting this. I'll take a look at what is going on ASAP. hmm... well, the plot thickens. I was able to recreate the "Unsupported data size 65536" message and now trying to understand why the check that causes it is there but - I wasn't able to get a crash, nor do I understand why this condition would result in a crash (it ends up returning -EINVAL)... :-( I am surely using a different tree though - I'm based on the cryptodev/master tree with cherry picking of just R-Car ccree clocks and enabling. I was thinking maybe it's a fix that is already in upstream cryptodev tree but not in your tree but didn't manage to identify any obvious suspects What tree are you based off?
