Ubuntu installation hanging on reboot? Try Ubuntu Server 21.10 [NOW BROKEN!]

[rhaleblianbeta]

This relates to threads here about hanging on boot due to a kernel change that does a new register access that hypervisors do not expect.

This page provides a release with an old enough kernel to avoid the problem:

https://ubuntu.com/download/server/arm

Specifically:

             Download Ubuntu 21.10           

This one will succeed in rebooting after initial installation.  You'll eventually get a new kernel installed next to the original, and you can make sure to select the original kernel in the boot loader menus when booting up.  Or you can modify GRUB to select that one.

Argh, this is a Live ISO, and it looks like it now includes a newer kernel that breaks us.

Sorry folks!

More exactly, it appears that the Live CD initially contains 5.13.0-19, which works, but that gets whacked during installation updates to 5.13.0-37.
