Hi Herbert, we see the following error messages in syslog on the current next kernel: Jun 05 13:15:20 a35lp62.lnxne.boe kernel: basic hdkf test(hmac(sha256)): failed to allocate transform: -2 Jun 05 13:15:20 a35lp62.lnxne.boe kernel: alg: full crypto tests enabled. This is intended for developer use only. The first one seem to be failure, but I can't tell where..... I don't see any other typical selftest failure messages. -1 is ENOENT. It might be related to the recent changes with sha256 being now in a library... The second one is probably because the full selftests are now enabled by default. Does it make sense to output this message now anymore at all?
