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.

Hi
This bug was filed for a very old kernel or the bug is old itself
without resolution.
If you can reproduce it with
- the current version in unstable/testing
- the latest kernel from backports
please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
Regards,
Salvatore
