Damn i love you guys. Was in a weird situation when i upgraded to my Epyc 9554 and my server ws not reachable. Debugged the whole day (not an expert) until i nearly gave up and found this thread. Reverted back to 6.12.6 - since the workaround would not work for me, same issue.
Server is now up and running i really considered some issue with my hardware.
Again, thx for finding the root cause ! I will warch rhis Thread and wont update until then.
