When using the newer kernel it freezes before splash. I did my best to follow instructions to create a crash file but none were ever created. Booting to recovery mode with 5.8 works, 5.4 kernel works. Booting from USB the (safe graphics) option works but not the default. On that USB I have latest available daily build (Oct 21 2020) of 20.10. I tried a fresh reinstall of Ubuntu 20.10 and still getting stuck.
