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.
