Package: linux-image-4.19.0-6-amd64
Version: 4.19.67-2+deb10u1

This issue looks like it might be related to #657689, or at least the
symptoms are similar.

Periodically, my network link goes down for ~35 seconds at a time. I
have not been able to determine what traffic pattern or set of other set
of circumstances that causes this and it doesn't happen on a regular
schedule. It could happen dozens of times an hour, then not happen for
many hours.

Here is the most recent sample of the error from my kernel log:

I did not really notice this issue until I placed the interface into a
bridge (which it shares with qemu-kvm virtual interfaces to bridge them
to the physical network). Placing it into the bridge adds 30 seconds of
bridge learning/listening time that exacerbates the issue and makes it
much easier to notice.

To clarify, this driver issue causes the physical interface to be down
for ~5 seconds only. However, during that time the physical link
appears down to the bridge, which then adds another 30 seconds of
downtime after the physical link is restored.
