I am also hitting this same issue, with the same USB ethernet device
that the bug opener is also using. According to additional discussion
here, https://forums.raspberrypi.com/viewtopic.php?t=282750, and here,
https://github.com/raspberrypi/linux/issues/3401, the bug appears to
still be active.  Any chance Canonical can work with the raspberrypi
linux project to get this fix upstream?

This happened on an adapter connected to a 10/100 ethernet switch providing 
connectivity for two devices. 
I can provide further logs upon request.

my crash is here:

  Kernel in use: 5.13.0-22-generic (linux-image-generic-hwe-20.04-edge)

  The weird part is that happens (not 100% sure yet) when Video
  conference is being made inside my home network. This USB NIC is
  connected to internet provider router and the onboard NIC to my
  private network (I use a mini PC, Gigabyte Brix, as a home
  router/server).

  I've tested one week ago with another USB 3.0 Gigabit NIC, which has a
  different chip from Realtek, and the same thing happened, so something
  is going on here. Also, I've tried a fresh install of Ubuntu 20.04
  (server) and the same thing. Another thing I've tested is to switch
  Nics, the public and the private, same problem.

  Any idea how to fix this? Is a mayor problem really.
