Comment 84 for bug 1799988

Not sure if this might help... looks like this Dell has some hardware design problems - we should be able to come up with a workaround nonetheless. I've had the stock Ubuntu kernels die on me several times - goes into what seems to be disk thrashing (on an SSD?!) and 50% of the time the OOM killer recued it - but only after 30-60 minutes, nobody can wait that long - with nothing in the logs to go on, so I compiled my own kernel to dig deeper.

Which brings me here - Wifi + Bluetooth missing, but only after several suspend / resume cycles -on my own kernel. This has only happened once over the course of 6 months with the Ubuntu 18.04.2 stock kernel. Correct me here, but it seems the Wi-Fi + Bluetooth is connected to the USB3 bus? My next step will be to load the USB3 driver as a module so I can unload and reload it to see if that resets it properly.
