[6.9.0-beta30] Kernel Panics with rtl8125

OS Version: 6.9.0-beta30

Processor: AMD Ryzen 7 PRO 4750G

Motherboard: MSI MAG B550 MORTAR

This is a bit of a duplicate post. I've been diagnosing some crashing behavior in another thread here. More recent developments seem to point at the rtl8125 driver and I thought that it might be best to bring that information here since I believe rtl8125 is a relatively new addition. I am seeing some syslog exception behavior followed by network messages in syslog. I think that the failures sometimes result in kernel panics that crash the whole system, but other times it seems to recover. Here is a log when it recovers:

I noticed that my server is occasionally doing a sort of "hiccup" behavior where it will stop responding to pings and the webUI entirely for somewhere between 10 and 30s.... Usually when I notice this, I assume the server has fully crashed since that is the error I am trying to diagnose. Sometimes the connection returns again without crashing. I've attached my diags as well.
