On non-RT, I've been unable to reproduce.
I haven't been able to hit the issue in 2/5 on RT on a v6.0 kernel in an x86 vm. Were there any other things running on the system besides pcrypt_aead01? More details about your environment and your kernel config would be helpful.
The first two patches seem ok but I want to think about the second more next week. I'll look over the rest of the series then too.
