Not sure if I have found another issue specific to Ryzen, or a bug that
manifests itself on Ryzen systems easier. I installed the latest
virtualbox from the ports and was doing some network performance tests
between a vm and the hypervisor using iperf3. The guest is just a
RELENG11 image and the network is an em nic bridged to epair1b
Then running in a loop
#!/bin/sh
while true
do
iperf3 -t 20 -R -c 192.168.19.18
iperf3 -t 20 -c 192.168.19.18
sleep 20
done
where 192.168.17.19 is the guest image, the box locks up solid after
10min to 30min of letting the script run. By lockup I mean the keyboard
is not responsive or anything. I can do this on two separate physical
machines (both ASUS MBs).
# ifconfig epair1a
epair1a: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST>

Any idea how to debug this to see if this is a hardware issue vs the
kernel deadlocking ? If I need to upgrade it to HEAD I can do so if need
be, but it would be nice to try and narrow it down first to a hardware
issue (its 2 different boxes) or software issue.
