Bug Description

[ Impact ]

 * Selecting certain resolutions causes hangs when an AMD GPU is connected to a display that supports FreeSync

[ Test Plan ]

 * Verify display with freesync doesn't hang anymore

[ Where problems could occur ]

 * AMD GPU could stop displaying

[ Other Info ]

 * This issue was reported upstream to AMD here: https://gitlab.freedesktop.org/drm/amd/-/issues/2162
 * It has been fixed in kernel 6.4-rc1:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=da5e14909776edea4462672fb4a3007802d262e7

 * AMD will CC it to stable to fix any remaining affected open stable releases, but as 5.19 is EOL upstream, want to ensure that Canonical picks up this patch in the 5.19 series as well.
