Public bug reported:

Ubuntu 19.04.  At least two applications that tie into and use _sensors_
info (including Psensor and another I cannot find the name of), plus
command line "sensors" report a Vcore of ~+0.4 to +0.7V on a Ryzen 7
2700X on an Asrock Taichi X470 mobo.  This is WAY below spec, yet the PC
is performant.

However, when in the BIOS, Vcore can be seen to be in the ~1.4-1.5V
range.

This behavior is consistent with _lm-sensors_ simply reporting a Vcore
that is a full 1.0V less than the actual value (e.g. reporting +0.5
instead of +1.5).
