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?

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?
