    I'm trying to get ardour running. It requires jackd, and also requires that
    jackd be run as the same user it is to be run as.

    I've built a new 2.6.10 kernel using kernel-package, installed it and biited.
    The I downloaded teh realtime-lsm source package built it and modprobed the
    resultant module. Yhis seemed to go OK. I used:

    modprobe realtime gid=29. Now lsomd shows the modules as loaded:

    stan@yogi:/usr/share/doc/kernel-package$ lsmod | grep real
    realtime 4752 0
    commoncap 5504 1 realtime

    But if I try to start jackd with:

    jackstart --realtime --driver=alsa

    I get the following:

    jackstart: cannot get realtime capabilities, current capabilities are:
               =ep cap_setpcap-ep
                       probably running under a kernel with capabilities disabled,
                       a suitable kernel would have printed something like "=eip"

    Can anyone tell me what I'm doing wrong here?
