I've got a good system up and running under F14, but I can't boot the rt-kernel. I've tried: vmlinuz-2.6.33.4-106.rt20.1.fc13.ccrma.x86_64.rt * - rtprio 99 * - nice -10 * - memlock 4000000 in limits.conf and pci=noacpi acpi=off It's a desktop 64-bit machine, that runs perfectly otherwise. Any ideas? Don
