[Bug 1888097] Re: bootloader install failed, installer crashed

[Richard Elkins]

I have an Acer Aspire 5 4700U octacore APU, graphics included on-board.

My installation did not crash per se.  It froze at the point where it
was going to begin writing to disk, displaying something wild about
finding a lot of disk partitions.  The mouse, touchpad, and keyboard
were inoperative.  I wish that I had taken a photo!

My successful work-around to install 20.10: 
* Install 20.04.1
* Bring it up to date.
* Turn on considering development releases somewhere in synaptic.
* update-manager -d

Now, I am on 20.10.

More good news for me:
* Kernel 5.8 succeeds (where kernel 5.4 failed) detects that I need an amdgpu video driver.
* Suspend followed by Resume works on 20.10; it did not on 20.04.
* Power management works on 20.10; it did not on 20.04.

Finally, I can close the lid, open the lid, walk away, come back - all
these power mgmt functions work just as well on Linux as they did on
Windoze.

  crashed.
