My Dell Latitude e7440 (core i7 4600U, intel graphics) shows a similar behaviour after updating to 18.04:
Wake-up after suspend often fails with power LED on. Hard shut down seems to be the only way to recover. Sometimes, additionally to this, suspend seems to incomplete in the sense that the laptop gets hot and the fan is running. The last entry in kern.log during the failing suspend is: PM: suspend entry (deep) While the issue shows up often, I did not figure out how to deterministically triggers it. I'm using the current kernel 4.15.0-38. Should this one contain the above discussed fix? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1774950 Title: Suspend fails in Ubuntu and Kubuntu 18.04 but works fine in Ubuntu and Kubuntu 17.10 (and on Kubuntu 18.04 using kernel 4.14.47) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1774950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
