On cold start my board Gigabyte B550 Vison D with Ryzen 5600X just loads the iwlwifi driver, not the igb. When I restart it loads the igb not the iwlwifi.

Can you attach both lspci outputs with more verbose info ? lspci -vvv
Also, can you please test with the latest 5.15 which is 5.15.62 as of this writing.
Unfortunately it seem to be a hardware problem. I have checked the behavior with another distribution (Kubuntu boot-stick). The same problem appears. If I start cold, in Bios the LAN is not shown. If I re-start (warm start) the LAN information is shown in BIOS. Yes I have upgraded the kernel to 5.15.62 now. If you assume that it is still a kernel problem, I will send requested information.

Done
Thanks, there is a race condition fix released in 5.15.63 for igb. Would you mind testing that, and also the latest 5.19.7? If they both fail, can you do a bisect from the last working kernel to the first non-working kernel?
I tried both Kernels without success. Always the same result. There was no older kernel working with this mainboard in the past. It was a new bord I tried out. I started with chroot fromm Ubuntu with the same problem. So I returned the Board now. If I get an identical board, I test it again and report the result. If I get a refund, I buy another board I think.
