With Ubuntu studio with 2.6.24-19-rt and 600MB in limits.conf and qjackctl that calls /usr/bin/jackd -R -P60 -t1000 -dfreebob -r44100 -p256 -n3 -D, 1Gb Ram.
I have only one firewire audiocard running with freebob.
Everything works fine with the recording of four track of a song; but at fifth when I push the stop button after a track recording ardour disappears.
Sometimes it generates an xrun, and sometimes not.
Here it’s my ardour.rc file:

Here it is how I run ardour:

here it is a log window that i see when i run ardour:
[error] no devices found for driver alsa.
If I create a new song (session) and I record a new track I can record and listen what I recorded.
I had this problem with ardour 2.3 and I still have it with ardour 2.5.
Any suggestion?
