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.

No, unfortunately I haven't.

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
