Just wanted to share my observations. At least on my machine, "failed resumes" are appearing in series after initial BSOD (black screen of death), which usually occurs after a long suspend.
After some experimentation, I've found that full/proper shut-down and boot-up cycle (in addition to the forced power-down after the initial BSOD) fixes the issue until next BSOD occurs. My guess is something in kernel 4.15.xx triggers the BSOD and messes suspend-resume parameters in EFI until it's re-set by the procedure mentioned above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1757445 Title: Suspend does not always resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1757445/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
