Unfortunately I need to do exactly that, as 6.8.1 breaks hibernation on ThinkPad T14 AMD Gen 1: [regression] 6.8.1: fails to hibernate with pm_runtime_force_suspend+0x0/0x120 returns -16 https://lore.kernel.org/linux-pm/12401263.O9o76ZdvQC@xxxxxxxxxxxx/T/#t No luck with kernel upgrades these days. :( I will backup the test filesystem so in case something breaks I can recreate and repopulate it again. Downgrading to 6.7.10 then and will see what happens. Can repopulate from backup again if need be. Also when upgrading to 6.8 again after the regression has been fixed. Best, -- Martin
