Ryzen issues on FreeBSD ?

[Lukasz]

I had the same issues - hard lockups after couple hours of work
(different loads).

My platform is:
OS: 11.1 and 11.2 (amd64)
CPU: AMD Ryzen 5 1400 Quad-Core
Motherboard: AX370-Gaming K5
ZFS pool: 10TB
BIOS: default settings (HT on)

After only upgrade to the newest BIOS everyhting works as expected - no
lockups at all. Now the machine has 47 hours uptime with zfs snapshot
received and  zfs scrub completed.

Regards,
Lukasz
