This started happening after updating pulling recent changes. It has also been confirmed to be happening on the beagle bone black: http://www.spinics.net/lists/linux-iio/msg18580.html If you look further into this thread you will see a workaround patch that I came up with: http://www.spinics.net/lists/linux-iio/msg18583.html Though this fix stops the reported events in userspace, interrupts are still occuring repeatedly. Does anyone have any suggestions beyond what I have done to remedy this issue? Regards, Michael
