I'm experiencing sporadic NIC failures when waking from suspend-to-RAM. Concretely, when it happens (maybe on every 3rd suspend operation, so reasonably/annoyingly often), the network driver completely locks up and no connectivity is possible. Sometimes I'm able to recover by rmmod and modprobe, but in 90% of the cases this also is not possible and I have to reboot to get the NIC working again. Note also that the system will go into shutdown but systemd then hangs somewhere, needing me to issue a hard reset.

Any advice on how I can support debugging this issue is greatly appreciated. Thanks!
