Bug description:
I configured Ubuntu Studio according to the howto (also using
ubuntustudio-controls) for the realtime recording. Then I wanted to check if it
works, I configured JACK using qjackctl (onboard soundcard, basic
non-low-latency settings, just to check if it works - normally I would plug-in
my M-Audio firewire card, which doesnt work atm because of ffado), but Jack
crashed with error "Post-shutdown script terminated with exit status=256". So I
opened the terminal and launched qjackctl from there, only two messages
appeared - "Suspending PulseAudio" and then "Bus Error" (when it crashed). I
googled alot but I haven't found (yet) the solution for this, I only found
other people on the web having same problems. The "real deal" is, that after
jack crashes, whole system gets very slow and unstable, applications tend to
crash, I also got my system crashed to the gdm once. Same error occurs when I
launch jack from terminal (ex. jack -R -d alsa).
My system specs: Ubuntu Studio 9.10, kernel 2.6.31-9-rt, AMD Turion64 2GHZ 1GB
RAM (ASUS A6KM notebook), onboard soundcard (alsa driver used in jack)
