I don't see 5.14 OEM supported in official repositories, could you point to exact steps ? Also, the system seems stable for some days with all below switches but battery life got worse, could you point to exact ones I can try to get rid off with 5.14 kernel ? BOOT_IMAGE=/vmlinuz-5.10.0-1057-oem root=/dev/mapper/ubuntu--vg-root ro intel_idle.max_cstate=4 i915.enable_psr=0 i915.reset=2 tsc=unstable quiet splash Also could you point to some resource how exactly cherypicking from OEM to mainline Ubuntu kernel works so we, the community could support this by testing with better understanding of underlying processes ?
