    Thanks !

    Do we know what the bad interrupt maps to ? Also what is the value of
    NR_IRQ and do you have SPARSE_IRQ enabled ? Can you try with the latter
    disabled and NR_IRQ set to something large, such as 128 ?

    (You may be able to check the interrupt mapping in debugfs)

    Cheers,
    Ben.
