No. Hosts.

I have several 6core/12thread Ryzens which are used for development 
testing.

They all use identical userspace with the sole difference being the 
kernel. They all use a selection of 5.x because 4.19 does not support 
the hardware properly.

The 4.19 testing is done on my old "test farm" which is all A8s and 
Athlon X760.

OK. I will upgrade one of my systems to Debian testing to try to 
reproduce this.
