Description of problem: The computer is unusable with rngd drawing 100% of cpu. Version-Release number of selected component (if applicable): 5.2.9-200.fc30.x86_64 #1 SMP Fri Aug 16 21:37:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux How reproducible: Fresh install from 29 to 30 on a macbookpro late 2013.
I see the same issue of rngd occasionally starting to use 100% of CPU until I restart the service. This is particularly annoying, because if it happens it drains the battery pretty fast. This is with Fedora 30 on a Dell XPS 13 with: rng-tools-6.7-2.fc30.x86_64
Other interesting tidbit: I have a Yubikey Nano in my laptop and it seems that rngd has at least some logic to gather entropy from smartcards. Maybe it is related. This may be related to https://bugzilla.redhat.com/show_bug.cgi?id=1739730

Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
