[Bug 1743094] Re: [regression] hibernation (freezes on resume) due to PTI
If resume is performed and only the graphical interface is crashing (so you can switch to text console, and you have your processes running), then it's probably a different issue. The original problem described there is that after resume the computers were simply frozen, not responding to anything. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1743094 Title: [regression] hibernation (freezes on resume) due to PTI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1743094/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@denisp, what do you mean "broken and lost after the resume?" What specifically is occurring?

For me hibernation doesn't work with 4.14.15-041415-generic Kernel. However the symptoms are different than with other kernels that have problems with hibernation post 4.13.0-21 kernel, with 4.14.15 the resume from hibernation is performed but my gnome session is broken and lost after the resume.

Works fine for me with 4.14.15-041415-generic. I did not try disabling PTI with 4.13.0-26-generic. Also, I'll note that I only noticed this problem after updating my BIOS (including the latest Intel microcode update and Intel ME patch).

Keep in mind that the 4.14.x PPA kernels also have PTI enabled, still hibernation works fine with them. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1743094 Title: [regression] hibernation (freezes on resume) due to PTI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1743094/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Unfortunately, "nopti" (GRUB_CMDLINE_LINUX_DEFAULT="nopti loglevel=7 no_console_suspend") does not at all make a difference for me.
