This issue is probably related to the Wacom driver w8001 (see [1] and [2], thanks [3]).
When I tried `cat /dev/input/mice` in console, system crashed in the same way as in X, but I got at least some error message (see attachement).

I can use the stylus to move the cursor – but when I touch the screen with it (i.e. click), the system immediately freezes. When I touch it without X, in the text mode (Ctrl+Alt+F1) it does not freeze. I tried to debug it over network, but the network also freezes at the same moment. When I try QubesOS (with kernel 4.1.13-9.pvops.qubes.x86_64) on the same machine, the stylus works correctly and the system does not freeze. Any tips how to debug it? Maybe using the serial port (I have the docking station with RS232). Or I can try some older releases and find the last one that was working if it helps.
