I think that the issue with VT-switching is not fixed by the commit, but by
another measure, that is switching to a text console before hibernating (the
script I use has an option to do this). T

Unfortunately with the patch applied to 6.3.4 it causes the old problem. The
screen stays dark, USB keyboard offline when trying to resume. So special

I believe my last issue regarding hibernation after this rewrite has been fixed
somewhere in linux-stable 6.2.13: The desktop no longer freezes when
VT-switching after resuming from hibernation.

Ok. After some tests with 6.1.8 and later, things seem to be a bit more stable,
though I do not know whether the reason is actually the newer kernel or more
exact tests on my part.
