Something else that you might want to try is 12.0-CURRENT.  There might
be some changes in HEAD that need to be merged back to 11.1-STABLE.

Temp works as expected now. However, a (similar?) hang building Samba47.

ctrl+T shows

Going to try the RMA route and see if the replacement CPU avoids this
problem.

It looks like this thread got mention on phorix :) In the comments
section (comment #9) a post makes reference to

http://blog.programster.org/ubuntu-16-04-compile-custom-kernel-for-ryzen

I guess Linux is still working through similar lockups too :(
