[LAU] jackd vs. kernel 2.2.26.6-rt11 vs. ALSA 1.0.18

Hi all, I experience a problem when trying to stop jackd with this setup * kernel 2.6.26.6-rt11 * alsa-lib/headers/tools/utils 1.0.18 * jackdmp current SVN and/or jack-audio-connection-kit-0.109.x * ICE1712 M-Audio Audiophile I already replaced the in-kernel alsa driver (1.0.16) and compiled alsa-driver 1.0.18 - all running fine. The problem occurs only when I want to stop jackd. ------ ^Cjack main caught signal 2 port deleted: M-Audio-Audiophile-24/96:midi/playback_1 port deleted: M-Audio-Audiophile-24/96:midi/capture_1 ------ .. and there it hangs dmesg says: ------ rawmidi.c:196: rawmidi drain error (avail = 4095, buffer_size = 4096) ------ Now, I cannot kill that jackd process ------- └» killall -9 jackd └» ps -A|grep jackd 7060 pts/0 00:00:00 jackd ------- Still there... therefor I also cannot shutdown the system cleanly. Only sysrq+reisub I do not know if that is a bug in the kernel or in alsa-lib. I don't think it's jackdmp, as I also tried "old" jackd, and two versions of alsa-driver, so that shouldn't be the cause either. Any ideas or similar issues? Thanks, Thomas
