With these details in mind I was able to repro this within seconds on my 16Gb machine,
basically by doing a stress in parallel:
stress -m 2000 --vm-bytes 20M --vm-hang 10 --backoff 1000
while true; do sudo ifconfig enp1s0 down; sudo ifconfig enp1s0 up; done
in 5-10 seconds I get

Thats already with the patch applied, so no panic and next "ifconfig up" recovers the device state.
I will submit a bugfix patch for that solution, but will also continue looking into suspend/resume refactoring.
Thanks,
Igor
