Hello, I have a problem with new I-pipe patch, which was not existing with legacy patch on 3.14 kernel, on BeagleBone platform.
When GPIO pin is configured as input with edge interrupt enable, on IRQ occurrence the following message appears: [ 303.331386] irq 88, desc: dc1be400, depth: 0, count: 0, unhandled: 0 [ 303.331401]
