The correct solution to the problem I've been facing was finally solved on comment #58, thanks @prasanth-s-cmi. I've contacted the kernel developer responsible for these patches introduced around Linux 4.16.1 on https://bugzilla.redhat.com/show_bug.cgi?id=1571330 , and he will blacklist my laptop model (Lenovo G40-80) for newer versions of Linux. Meanwhile, `ahci.mobile_lpm_policy=0` can workaround this problem.
