ah sorry, my bad. of course the handler is called forever:
mvebu_gpio_to_irq pin=8
mvebu_gpio_irq_set_type pin=8
mvebu_gpio_edge_irq_unmask
mvebu_gpio_irq_handler irq=103
mvebu_gpio_level_irq_mask irq=103
mvebu_gpio_irq_handler irq=100
mvebu_gpio_level_irq_mask irq=100
mvebu_gpio_irq_handler irq=101
mvebu_gpio_level_irq_mask irq=101
mvebu_gpio_irq_handler irq=102
mvebu_gpio_level_irq_mask irq=102
mvebu_gpio_irq_handler irq=103
mvebu_gpio_level_irq_mask irq=103

yeah, if i disable gpio-leds, gpio-keys and gpio-fan the hang will disappear.
But once i enable one of it the board hangs again.
