Hi folks,
	I have been running into some deadlock issues on Ryzen boards.  The
most easy way to trigger the problem is to compile net/samba47 from the
ports.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225584

Varying the load sometimes allows the compile to finish, but most of the
time the compile deadlocks.  I have seen this both on RELENG_11 as well
as HEAD from r328611

Any ideas how to possibly work around this ?

	---Mike
