Just a hunch, try this please

I patched the Tubleweed 5.12.10-1-default kernel driver so that I don't have to build the whole package. No success, the network stack froze even with this patch. The only remedy so far is the autosuspend disable. -- You are receiving this mail because: You are on the CC list for the bug.

Could you try to apply both Oliver's and my patches?

Yes, I'm testing. BTW, the frequency of deadlocks with the new docking station (or rather a port replicator - https://i-tec.pro/en/produkt/c31dualdockpd-2/) is high enough to call the scenario a reliable reproducer. -- You are receiving this mail because: You are on the CC list for the bug.
