I got this too.

The following fixed it for me:

Index: sys/arch/x86/pci/amdsmn.c
===================================================================
RCS file: /cvsroot/src/sys/arch/x86/pci/amdsmn.c,v
retrieving revision 1.2
diff -r1.2 amdsmn.c
104c104
<       amdsmn_rescan(self, "amdsmn", &flags);
---
>       amdsmn_rescan(self, "amdsmnbus", &flags);

then I was able to boot a live usb stick and envstat showed the CPU
temp as expected.

Cheers,
