Thank you for trying the suggestions. I guess Zhang will take over again, just three more comments.

1. The new portable devices are missing a serial port and also an Ethernet device. So getting messages out – serial console, netconsole – don’t work. An EHCI debug gadget [1] will (probably) also not work as all USB ports are probably xHCI ports. You could look for xHCI debug cables.

2. Please contact Dell and make them aware of the problem. That’s really important in my opinion.

3. You could try `systemctl suspend; sleep 10; systemctl poweroff`. Hopefully messages are stored by the systemd journal, and on new start you can retrieve them with `journalctl -a -b -1`.
