    Hi,

    I have been looking and searching the latest kernel pachecs and update for
    the fixes that were issued some time ago, but I have yet to see them.

    The patches were issed by Henk De Groot and were as follows...

                            wake_up_interruptible(sk->sleep);

    These were, I believe, issed against the 2.4.17 kernel.

    These were to fix a lock up problem that I have encountered when useing an
    scc card and the scc utilites but might have been more general to ax25 use.

    Have I missed something and they are there in the kernel now, haven't seen
    anything listed in the kernel changes or are these fixes being incorporated
    in the 2.5.xx series.
