A particular RX 5600 device requires a hack in the rebar logic, but the current branch is too general and catches other devices too, breaking them. This patch changes the branch to be more selective on the particular revision. See also: https://gitlab.freedesktop.org/drm/amd/-/issues/1707 This patch fixes intermittent freezes on other RX 5600 devices where the hack is unnecessary.
