    It looks like its either the interrupt transfer code (highly likely)
    or its the suspend/resume support (less likely).   Judging from
    the NetBSD commits, the interrupt transfer code is still buggy and
    under active development.

    We should probably not try to bring the interrupt transfer code in
    for at least two months.

    There are a few bits in the 1.85 through 1.88 range for ehci.c that
    look ok to bring in, if you want to have a go at that.  I audited
    everything above that and brought in a few things.
