Hi @keihengfeng, Could you build a test kernel with the two test patches here applied:
https://git.kernel.org/pub/scm/linux/kernel/git/luto/linux.git/log/?h=nvme/power&id=1115e17962c597d8e6dd140d903a51a58d0ec2c0 I'd like to get some testing to see whether that works on the problematic Samsung and Intel machines. (Those delete the quirk and replace the APST table computation with something closer to what Intel RSTe does.)
