I've been using the 4.18.0-12-lowlatency kernel from cosmic and not had any freeze-ups in the last 48 hours. I'll continue monitoring and report back after a few more days.
Because there are lots of reports of Intel Baytrail CPUs suffering freezes due to c-states I want to make clear the CPU here is Broadwell: model name : Intel(R) Core(TM) M-5Y71 CPU @ 1.20GHz -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1803960 Title: 4.18.0 kernels hang system randomly Status in linux package in Ubuntu: Triaged Status in linux source package in Cosmic: Triaged Bug description: I've been using 18.04 on an Asus T300CHI without issue until I decided to switch to the v4.18 kernels from 18.10 via linux-image-lowlatency- hwe-18.04-edge. Since then the system randomly but regularly completely hangs. Only a hard power-off resolves it. Frustratingly there are never any clues in the kernel logs so it is very difficult to point to anything that might cause it; there is never any obvious pattern in the workload, the user interaction, or state of the PC when the hang occurs. A week ago I switched to the Ubuntu mainline v4.19 builds and that resolved the issue. I was reminded of it again today when it hung a few minutes ago. After the reboot I checked the previous boot log and realised the PC had accidentally been booted with the default v4.18 kernel rather than v4.19. I don't think this report can be debugged but it is worth having a tracking bug in case other people experience the same issue with v4.18.
