Just curious: what CPUfreq governor do you use by default for the LibreELEC kernel? Your patch greatly improves the stability I'm seeing, but doesn't quite elimitate it. I'm testing suspend/resume in a loop on VIM3, and with schedutil (default) or ondemand, it eventually hangs. With either powersave or performance it's stable. Kevin
