Hi! I found an older discussion on the same topic, where it is mentioned that the same problem also occurs on imx6dl, imx6d and imx6s: https://linuxlists.cc/l/4/linux-crypto/t/3843436/caam_rng_trouble#post4282922 I have also observed the problem on an imx6dl, running a 5.10.112 kernel. Therefore, the problem might persist for the other variants. BR BB
