Hi all, just a note: A got it more or less working. This morning I installed the vanilla-2.6.14-rc4 and I could start jackd in realtime with -n6 -p256 and run ardour and qsampler/linuxsampler in parallel without an xrun during normal operation. It just crashed jackd when I used -n6 -p128 but even after that it didn't ruin the sounddriver so I could start jackd again. That really takes a big stone from my heart as I have to do some serious music with the laptop this weekend and I feared I had to mess around with my old one... So thanks for your patience, Arnold -- visit http://dillenburg.dyndns.org/~arnold/ --- Wenn man mit Raubkopien Bands wie Brosis oder Britney Spears wirklich verhindern könnte, würde ich mir noch heute einen Stapel Brenner und einen Sack Rohlinge kaufen.
