[PlanetCCRMA] JACK isn't getting realtime

[Jon B]

(I got my Echo Indigo IO card today, and it seems to work nicely.)

But I just noticed that JACK isn't getting realtime capabilities:

00:12:49.149 JACK is starting...
00:12:49.150 /usr/bin/jackstart -R -dalsa -dhw:2 -r48000 -p512 -n2
00:12:49.155 JACK was started with PID=6280 (0x1888).
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"
back from read, ret = 1 errno == Success
jackstart: could not give capabilities: Operation not permitted
jackd 0.99.36

I thought this was built in to the kernel by default?  Where do I look first?

Also I get these:

delay of 24737.000 usecs exceeds estimated spare time of 10581.000; restart ...
delay of 24803.000 usecs exceeds estimated spare time of 10581.000; restart ...

Is that related?
