Comment 31 for bug 2022826

Interesting to compare the old computer & the new computer for ethernet using lspci -nn.
Old computer:
02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller [10ec:8125] (rev 05)
03:00.0 Network controller [0280]: Intel Corporation Wi-Fi 6 AX200 [8086:2723] (rev 1a)
New computer:
01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 15)
02:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:0608]

I found a web page re AMD Ryzen & Ubuntu to fix constant crashes:
https://www.servethehome.com/amd-ryzen-with-ubuntu-here-is-what-you-have-to-do-to-fix-constant-crashes/
But it dates back to 2017. So is it worth trying given that it refers to an old kernel version 4 and not the current version 5?
I've also found a reference to installing AMD GPU drivers at:
https://askubuntu.com/questions/1432449/how-to-install-amd-gpu-drivers-ubuntu-22-04-lts
Could this be relevant, especially as I don't do gaming?
