Comment 10 for bug 1877889

The drm-tip directories for the most recent days have missing or failed amd64 builds, so I had to go back a few days and install the drm-tip kernel from: https://kernel.ubuntu.com/~kernel-ppa/mainline/drm-tip/2020-05-20/

With secure boot disabled I have rebooted approximately 15 times and have not been able to reproduce the hang on boot issue I was seeing with the regular 5.4 kernel. This is an intermittent issue, so I'll keep using this kernel for the time being and let you know if it hangs again.

I have some questions now:

1. Should I expect the fixes from this drm-tip kernel to be made available to the regular Ubuntu 20.04 GA kernel (v5.4) ? Or, will the fixes only be made available in the next 20.04 HWE kernel?

2. How safe is it to keep using the drm-tip kernel in the meantime? I imagine the drm-tip kernel is not as thoroughly tested as the regular kernel, and does not receive automatic security updates.

For reference, these are the packages I downloaded and installed.
