With this patch and IRQF_TRIGGER_LOW | IRQF_ONESHOT, I get an interrupt

completes successfully.
That shouldn't happen :-(
With this computer nothing is normal. Every single component except the
CPU, display and USB has major issues under Linux.
On all the panels I've tried, with or without GPIO, turning the
interrupt to active low works. How about Windows, have you tried if it
works there?
Yes, the Wacom digitizer works fine under Windows.
Can you send output of /sys/kernel/debug/gpio when after the kernel has
disabled the interrupt?
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.
