/proc/sys/crypto doesn't exist, so anything checking the status of /proc/sys/crypto/fips_enabled fails terribly. (Specifically trying to bring up a FreeIPA server which includes tomcat-based Dogtag CA, it checks for FIPS during setup, dies).
I see there is an rk_crypto kernel module available, so I don't know why /proc/sys/crypto itself is missing. I tried 'modprobe rk_crypto' and it loaded (appears in output of 'lsmod'), but /proc/sys/crypto still doesn't exist.
