With this computer nothing is normal. Every single component except the
CPU, display and USB has major issues under Linux.

Yes, the Wacom digitizer works fine under Windows.

Attached. The kernel message I get is "byt_gpio INT33FC:00: Gpio 56
interrupt flood, disabling".
I also get a "byt_gpio INT33FC:02: Gpio 18 interrupt flood, disabling"
before which seems unrelated.
