constantly. I found i few older Topics in the Forum but nothing conclusive. Looks like it es fairly recent. What i did found was some discussion here https://bugzilla.kernel.org/show_bug.cgi?id=213377 and here https://bugzilla.kernel.org/show_bug.cgi?id=213651. People in there talking about very similar if not the same hardware and wondering if these "fixed" recently reached the stable kernel and is causing the problems i have after i updated the system/kernel to the version where those "fixes" are introduced

Looks like it appears mostly after returning from hibernate/suspend mode. After a clean reboot it looks like to be ok.

ceterum censeo: do you have a parallel windows installation?

No issues w/ the lts kernel? You can try to downgrade to 5.14 (don't forget out of tree modules like nvidia, but otherwise the kernel downgrade should be fine)

Thanks @seth and sorry for the delay. I tried ethtool and it didn't help much and i don't really want to work with an "old" kernel. After fiddling around with it, it looks like it is mostly triggered by the suspend and a restart works almost every time and no i don't have a parallel windows installation or any other system parallel to my arch installation. I don't think there is anything left to do and this needs to be fixed upstream.

The downgrade/lts thing is to

identify/confirm the regression.
You'll likely be asked to https://wiki.archlinux.org/title/Bisect … s_with_Git it anyway (and catching it between two binary releases will lower the amount of required rebuilds)
