Comment 2 for bug 2077920

Thanks for the bug report. I can see two main problems here:

1. The amdgpu kernel graphics driver is emitting warnings that look like crashes.
2. The rtw_8821ce kernel wifi driver is flooding the system log (this is probably the performance issue).

So I can only suggest trying an older Ubuntu release like 22.04.0 with an older kernel:

  https://old-releases.ubuntu.com/releases/jammy/ubuntu-22.04-desktop-amd64.iso

or trying newer kernels from:

  https://kernel.ubuntu.com/mainline/?C=M;O=D

or disable wifi and use wired networking;
or replace the wifi card in the laptop with an Intel one.
