  To: gentoo-user

On a system where I can't use OSSv4 for sound (due to MIDI) and need to 
fall back to ALSA, I've hit ALSA's insane latency issues and therefore 
decided to use JACK.  I'm trying to set-up a machine suitable for 
music/audio production.

But JACK just stops working at random.  Sometimes it works, but after a 
a while it doesn't anymore.  And when that happens (which happens sooner 
rather than later,) restarting JACK (with qjackctl) doesn't help; only 
rebooting the machine does, which as you can guess is very annoying.

I'm appending the error message in case someone can help me figure out 
what's going on.

I'm on AMD64, kernel 2.6.35.1 (gentoo-sources-2.6.35-r1) using in-kernel 
ALSA on a SoundBlaster Live 24-bit.

I don't use jack (but I use alsa without problems) but this might help:
http://art.ubuntuforums.org/showthread.php?p=9717379
...maybe? Googling, also seems to indicate the need for a "realtime"
configured kernel (don't know if you got that or not)...

Best regards
