Subject: crypto self-test errors kernel 6.12.4

Hello,

I upgraded my ARM kernel from v6.6.9 to v6.12.4 and I am seeing some
crypto self test errors that I did not see before. Shown below. These
errors are different every boot and I did not see them on 6.6.9 kernel.
I did notice that when I compile the crypto HW acceleration drivers as
modules like this:
CONFIG_CRYPTO_DEV_ATMEL_AES [=m]
CONFIG_CRYPTO_DEV_ATMEL_TDES [=m]
CONFIG_CRYPTO_DEV_ATMEL_SHA [=m]

and have them loaded by systemd at boot I do not get errors and all the
self tests pass.

Is there a race condition I am not aware of? Or is the new asynchronous
crypto tests creating bugs in the HW acceleration drivers.
