[LAU] jackd process can't be killed

I'm running Debian Lenny on a custom 2.6.26.8-rt12 kernel. I notice once jackd starts, it cannot be killed. kill -9 leaves the jackd process in state DLs D Uninterruptible sleep (usually IO) L has pages locked into memory (for real-time and custom IO) s is a session leader Running jackd -R -P70 -dalsa -dhw:0 -r44100 -p128 -n2 -Xseq I get same behaviour from kernel 2.6.26.6-rt11. Running in non-RT mode shows same behaviour ice-1712 chipset M-Audio Delta 44 jackd version 0.109.2 tmpdir /dev/shm protocol 22 I built jack 0.116.x, alsa 1.0.18x, and still get same behaviour. This kernels alsa driver is 0.16, upgraded to current 1.0.18a, same behaviour. This whole situation is disheartening as I once had a working setup on an older Ubuntu distribution where I could use skype with alsa's jack plugin (yes, I know, Ubuntu doesn't ship it, I had to rebuild libasound2-plugins pkg), but other alsa/jack issues forced me to have to dump Ubuntu altogether. I discovered the inability to kill jackd process while trying to troubleshoot skypes use of alsa's jack plugin crashing jackd. Also discovered any process that invoked that plugin would crash jackd when the plugin thread disconnected from jackd. In all it seems my jack setup is now unstable. Any help in troubleshooting these problems would be appreciated, thank you. -- aRDy Music and Rick Dicaire present: http://www.ardynet.com http://www.ardynet.com:9000/ardymusic.ogg.m3u
