On Linux 6.2, Zen2 and Skylake, no issues or boot problems:
Tested-by: Tor Vic <torvic9@xxxxxxxxxxx>
Thank you for testing this. It’d be great if you shared the exact timing
numbers too. (Just to be sure, did you also test ACPI S3 suspend/resume?)
I have just tested suspend/resume on the Zen2 machine, it works.
Not yet tested on the Skylake platform.
What is the best and simplest way to get these timings numbers?
Kind regards,
Paul
