I suspect your embedded controller together with ACPI irq handling, but it is just guessing.
The freeze occurs on the XPS 13 9350 but not on the newer model 9370. And now that I know how to avoid the problem, it isn't a very pressing issue for me anymore. But if you suspect other devices might have a similar problem, I'm in for helping investigate.
I presume you don't have serial output available?
No, unfortunately I haven't.
May you please try some simple (non graphical) run scenario (usb_hid). If this also already get stuck when you press your keys, can you please setup the nova spinner setup for the nova kernel, see [0]. You will have to boot in non-UEFI mode (either USB or if not working try via PXE).
The usb_hid run scenario doesn't get stuck when booting in non-UEFI mode. I'm using the very convenient vga_log_drv (thanks to Johannes Kliemann!) the get an impression of the liveliness of the system - for reference see [1] and [2].
Out of curiosity I also tried to boot Sculpt in non-UEFI mode. The system doesn't freeze when pressing FN+F11/F12 but the display brightness decreases/increases instead.
So I guess the next step is to boot in UEFI mode with VGA log output enabled and setup the nova spinner?
Cheers, Roman
