Hi I'm seeing a bizarre issue that I've never seen before. Connecting MIDI source/sinks in QJackCtl, sometimes QJackCtl hangs. Badly. After a kill -9, QJackCtl won't die; 16101 tty1 DL 0:03 \_ qjackctl 16107 tty1 Z 0:00 | \_ [qjackctl] <defunct> 16109 ? Z 0:00 | \_ [jackd] <defunct> I've upgraded my QJackctl to 0.2.14, but still the problem persists. I'm not suggesting for a minute that this is QJackCtl's fault however: since this is such a bizarre fault, I though I'd like to check on this list that this really is a kernel bug :) thanks Rob PS. Suggestions for kernels known to work well for multi-channel audio and MIDI work welcome - and no, I'm sticking with Gentoo for now.
