Just updated FC30->FC31. Now I'm in a soft lockup boot loop.
Since I can't boot, no logs.
Just before the lockup:
random: crng init done
random: 7 urandom warning(s) missed due to ratelimiting
Something very similar was reported a year ago, but for older kernels:

More recently, some AMD CPUs had a busted hardware random number generator:

There were some follow-up stories about a kernel patch that intended as a
workaround for the buggy CPUs. Maybe the patch has landed, and it ain't
working?
