I've had these freeze issues for a while, and I've been following this thread for a while (comment #42 helped, though I still have occasional freezes).
And the timing of these bugreports/comments coincides with when these freezes started affecting me...
Long story short, we can try adding `ahci.mobile_lpm_policy=1` or `ahci.mobile_lpm_policy=0` to the kernel options in grub. Supposedly confirmed to help Lenovo G50-80, X250 and T450s. We have a G40-80 and T470s affected on this thread, and mine's a Lenovo G500s (similar to G50-80). Maybe it'll help? (praying that it helps)
It's possible that these freezes have multiple causes, and won't be completely fixed even if the workaround helps at all.

Googled "Fedora random freeze" today and found this: https:/ /fedoraproject. org/wiki/ Common_ F28_bugs# Certain_ laptops_ .28Lenovo. 29_hang_ randomly
Apparently an issue in Ubuntu also: https:/ /www.phoronix. com/forums/ forum/software/ desktop- linux/1020821- fedora- workstation- 28-is-shaping- up-to-be- another- terrific- update? p=1020982# post1020982
