If there are any easy-to-setup tests I could run to help identify this issue, I'd be happy to run some tests on a spare Banana Pi I have. If there really is a bug in the sun4i-ss driver or in the accelerator itself that causes data corruption, I'd rather have it found as soon as possible. @Correntin: Is it possible to let your cryptotest testsuite run tests specifically for large data blocks?
