Hi Christian
In my tests, I also saw the same issues with active-backup too.
Do you know a way to reproduce this issue? I'm having a hard time to find a consistent reproducer, currently I need to deploy a complete openstack, run a ser of load tests on it and eventually the problem shows up, but it takes many hours and not on all hosts.
It would be much easier to have just one machine and trigger the issue in some other way.
Also, this is fixed upstream, some changes between 1.8.x and 1.9.x of upstream source drivers fixed the problem (they are at 1.12.x now, so it has been fixed for quite a while now). The problem is that whatever the fix is, is has not been imported to kernels 5.15 (jammy GA), 6.2 (jammy HWE), 6.5 (cosmic GA). I could not reliably test upstream mainline 6.6 because there is no ubuntu currently shipping this package and the pure upstream kernel breaks a lot of stuff in ubuntu.
I mention this because of your post in the intel mailing list. They will probably not be able to help much.
Let me know if you find a consistent reproducer.
