Hmmm, yes - the patch fixes the crashes, i.e. no more crashes with
either sequence of module-loading, cat rng_available works as well,
but...

Having this patch active rngd complains:
	rngd[1435]: rngd 2-unofficial-mt.13 starting up...
	rngd[1435]: block failed FIPS test: 0x1f
	rngd[1435]: block failed FIPS test: 0x1f
	...
	rngd[1435]: stats: entropy added to kernel pool: 0
	rngd[1435]: stats: FIPS 140-2 successes: 0
	rngd[1435]: stats: FIPS 140-2 failures: 10

It doesn't do this without the patch.
The only available rng was via, I did blacklist the others just to be
sure.


regards
   Mario
