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
then
watchdog: BUG: soft lockup - CPU#0 stuck for 23s!
It sits for a while, then reboots. Rinse and repeat.
I've tried nomodeset as a kernel parameter. No joy.
Any suggestions appreciated.

Interesting that it eventually reboots itself.

Have you tried removing the "rhgb quiet" from the end to get more kernel output? Have you tried booting one of the F30 kernels instead?

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?
