Oh, you know what, I recall that when I upgraded Ubuntu-Studio did not properly set the permissions of /dev/shm, the shared memory directory. Can you verify the permissions of that? Mine is
[EMAIL PROTECTED]:~$ ls -l /dev | grep shm drwxrwxrwt 2 root root 40 2007-11-12 14:37 shm Does yours show the same? You might also run jack under strace, like so: strace /usr/bin/jackd -R -u -dalsa -dhw:0 -r44100 -p1024 -n2 I think this is where I discovered it could not open the shm directory and create files there.
