Currently, all the devices are running on an embedded platform (AMD Geode LX500) and works as expected. However, when introducing a 64bit KVM host for testing, all the 32bit hosts running on the Geode platform, report the following warning and drop offline temporarily. The CPU usage on KVM host spikes and all the CPU time is spent on the kernel threads servicing the WG interfaces. > > I'm using kernel 4.19.41 and have seen the issue with both the last WG snapshot as well building from master. Hi Ryan, Did you mean "AMD Geode LX800 @500 MHz" ? (ex. ALIX/net5501) If so, I have a couple of those using kernel 3.16.64 (i586) mixed with 3.16.64 (x86_64), and WG works well between them, no issues like you reported. iperf3 over WG runs at 23.8 Mbits/sec.
