Quality of drivers accepted into mainline kernely may vary, especially for rare hardware. I am ready to cooperate and help with improving this driver. Btw, I've googled thread from this mailing list https://www.spinics.net/lists/linux-wpan/msg02555.html "ping6 doesn't use at86rf230 driver" with somewhat similar issues, but it was spi driver's fault. Not sure if it's the same reason here, any ideas? Ok, so I've started one of the dev board, looks like 12 interrupts are fired, then something breaks and seems no more frames are sent, as interrupts count does not update and TX bytes value of wpan0 remains 352 Interrupt line from /proc/interrupts should be this one: 161: 0 GPIO 109 Level spi32765.0 at86rf230 spi32765.0: Detected at86rf212 chip version 3 at86rf230 spi32765.0: unexcept state change from 0x01 to 0x08.
