Just tested again with latest mainline, but no change. Once suspended,
keyboard becomes inactive and no longer accepts any input, so no way to
switch to tty to view dmesg. The only way to move forward after
suspending is holding down power to hard shutdown, then power back on.
I tried enabling persistence in the systemd journal, then checking
journalctl -k -b -1, but nothing is recorded from dmesg after the
suspend.
