OK, I think I progressed a bit: SUPER STRANGELY, awaking from sleep crashes only when I close the lid. My Dell latitude has Fn-sleep combo so I can suspend the laptop from the jeyboard, and then I have no crash. I tried several times and it repeatedly wakes up without problems.
BUT if I close the lid after the suspend (also when I suspend from the keyboard Fn combination), the laptop crashes when tries to wake. I can reproduce this. Googling around, I did not find any solution in linux, but several had the same problem in Windows: https://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/workstation-crashes-sometimes-when-lid-is-closed/2c3c38a7-dee7-4ee8-a233-a5031f59110c Which microsoft suggest waking USB driver, perhaps it is Intel USB 3.0 driver. I will update the BIOS and if the problem persists, I will open a new bug report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1801743 Title: Suspend fails in Kubuntu 18.04 but works fine in Kubuntu 17.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1801743/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
