Comment 20 for bug 1966870

I tried things once more, this time OVS wasn't active at all (in the former try it was active after boot and then disabled) - still failing.

Next I tried to use a different kernel(5.4.0-105-generic)

I don't know when in >5.4 this started to fail, it surely worked a few months ago already using the an HWE kernel back then and running the same tests that now stumbled over this.

I usually run with:
linux-image-generic-hwe-20.04-edge 5.13.0.27.29~20.04.13 => the one that initially failed

And now I cross tested:
linux-generic 5.4.0.105.109 => working fine

Would it be helpful to you to also get (it is somewhat suspicious that egde is behind non-edge):
linux-image-generic-hwe-20.04 5.13.0.39.44~20.04.24
Would there be any other build that I should try helping you to pinpoint this?
