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).
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 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. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1798961 Title: Random unrecoverable freezes on Ubuntu 18.10 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1798961/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
