(In reply to Marcus Meissner from comment #20) > it actually is on sle15 and leap 15. Hmm ... then the question rises: why do the fips test not restore the entropy level after the tests? It should be possible to save a copy of the current entropy and write it back after the tests, the kernel has an API exactly for this, see ioctl RNDADDENTROPY in man:random(4). Drain the entropy makes the system unusable.
