Damn, not entirely. I almost fried my Odroid (it survived 130 degrees of C)... The TMU supports only 4 trip points, so when I added two new trip points and reordered them... the last two (including critical) was not receiving interrupts. Polling mode is needed. I'll sent some patches soon... BR, Krzysztof
