Hi Axel,

There might be some useful information here:
http://sourceforge.net/apps/mediawiki/guitarix/index.php?title=Guitarix_Embedded_/_ARM_SoC
http://wiki.linuxaudio.org/wiki/raspberrypi

Fwiw, I'm using Jack1 myself on the Raspberry Pi with the default rtprio 
and memlock settings. And you don't get any errors or warnings before 
your system locks up?

Regards,

Jeremy
