Public bug reported:
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)
