from quick internet search 3.15 kernel is needed? but not specified
in .spec?
Hm, why 3.15?
Looking at the arc4random code it fallbacks to /dev/random and
/dev/urandom if syscall is not available (getrandom syscall was
introduced in 3.17).
Maybe sshd is not allowing access to these at that point?
strace could tell us something.
