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. ** Attachment added: "dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1799988/+attachment/5284639/+files/dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799988 Title: Missing wifi and bluetooth after sleep on XPS 9370 To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1799988/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
