Comment 15 for bug 2007718

6.1 from linux-oem-22.04c indeed fixes this suspend/ resume issue for me.

6.1 from linux-oem-22.04c doesn't feel as mature as 5.15 though, there is some repaint/ flickering screen bug that I haven't seen in either 5.15 or 5.19 (but was also present in mainline 6.1). It does seem somewhat more efficient on battery (purely subjective "measurement").
