Both preempt and ll are known to cause deadlocks on 2.4. If you want a rock solid system i recommend to go either with vanilla 2.4 or even better 2.6. There is an interesting thread about scheduling latency going on on fedora-devel: http://www.redhat.com/archives/fedora-devel-list/2004-June/msg00031.html Regards, Florian --- -> Florian Schirmer -> Software Developer -> NATIVE INSTRUMENTS GmbH -> [EMAIL PROTECTED] -> Schlesische Stra�e 28 -> http://www.native-instruments.de -> D-10997 Berlin -> Tel. +49-30-61 10 35-453 -> Germany -> Fax +49-30-61 10 35-35 ---- New products: GUITAR RIG - the complete solution for perfect guitar sound => http://www.ni-guitar-rig.com XPRESS KEYBOARDS - xpress versions of PRO-53, FM7, and B4 => http://www.ni-xpress-keyboards.com >>>>>> NATIVE INSTRUMENTS - Generate the Future of Sound! <<<<<<
