This is the start of the stable review cycle for the 6.13.3 release. There are 443 patches in this series, all will be posted as a response to this one. If anyone has any issues with these being applied, please let me know.
Builds & runs fine BUT fails to suspend to RAM 99.99% of the time (basically one success but never again). Display powers down but fans stay on. Tested on multiple systems, all x64. I first suspected amdgpu because why not :) but it also fails on a system without amdgpu, so that's not it. Reverting to 6.13.2 immediately fixes everything. Common symptom on all machines seems to be [ +0.000134] Disabling non-boot CPUs ... [ +0.000072] Error taking CPU15 down: -16 [ +0.000002] Non-boot CPUs are not disabled "Error taking down CPUX" is always the highest number of CPU, i.e. 15 on my 16-core Zen2 laptop, 3 on my 4-core Sandybridge etc. I started to revert suspects but no luck so far: - acpi parsing order - amdgpu backlight quirks - timers/hrtimers Suggestions for other suspects are welcome. -h
