    Subject2.6.14-rt15 @x86_64UP: "sem_post: Invalid argument"
    Date
    I get loads of those messages since switching from rt12 to rt15.
    no other known change.

    They happen during startup and when I trigger
    i.e. an ardour build like this:
    $ scons

    a typical strace excerpt:
    ----
    futex(0x5012a0, FUTEX_WAKE, 1) = -1 EINVAL (Invalid argument)
    write(2, "sem_post: Invalid argument\n", 27) = 27
    ----

    Other futex() calls like
    ----
    futex(0x3b384030c8, FUTEX_WAKE, 2147483647) = 0
    ----
    succeed.

    This happens on fc4.
    Maybe caused by a recent change from a semaphore to completion?
