Intel LAN i225, I am testing this controller, if I find a stable and fast setting for this type, I will add a comment. I downloaded the Intel manual for this controller, according to it I am testing the settings for a stable connection.
I solved a similar problem with drivers, first I installed the oldest supported driver, then it is necessary to install the newest one and it should be ok.
WHEA is a notification of errors between cpu and PCI-e, just change the processor settings so that there are no errors during data transfer. I have experienced when certain CPU overclocking settings force these errors.
I had a similar problem, caused by setting a high refresh rate on the 240Hz monitor, if I set it lower the problem disappeared and the boot screen was ok.
