Comment 32 for bug 1798961

I am encountering a similar issue on a new Dell G5 5587. I've installed Ubuntu 18.10 (fresh download today) alongside Windows 10 on a 1TB nvme SSD.

I can boot into Ubuntu, but the system hangs shortly after boot, usually less than 5 minutes. I have not determined what specifically triggers the hanging. I have noticed that it does not happen all at once. By that I mean that I lose mouse first (touchpad and wireless mouse), but I can still use the keyboard (sometimes) for a few seconds after the mouse is gone. This makes me wonder if the system is actually frozen or if there is just no HID being recognized. I've also seen the system "lag" input from the keyboard: no response immediately but 30-40 seconds later characters that I typed will appear. I also notice that the fans kick on high, so there may be a runaway processes.

In the current state 18.10 is unusable. I haven't even been able tail the log files, I encounter the hang before I have time to troubleshoot the issue. I'm not sure if it's the same issue or something specific to my hardware, I'll update as I continue to try to troubleshoot.
