    Subject[PATCH] 2.4.10-pre13: ATM drivers cause panic
    Hi,

    seems a couple of spin_lock(s) and a spin_unlock was missing.
    Why didn't this problem show up with earlier releases ???
    Anyways, please find a (quick) patch below. It would be great if this patch or
    any other similar could make it into the next release!
    Thanks,

    Immanuel
