I also see this warning on the X470-pro with Ryzen 7 2700 on 12.0-BETA.
But I don't get the Firmware errors below.

After kldload amdtemp I see the following sysctls:
dev.cpu.0.temperature: 77.1C
dev.amdtemp.0.core0.sensor0: 77.1C

The temperature I see in BIOS is much lower (maybe around 40.0C). Don't
know if just the offset is wrong or the numbers are completely bogus.

Numbers from sysutils/xmbmon look saner but not sure if they are correct.
