switched to the CCRMA RealTime patched kernel for use with Ardour / Jack.
kernel-rt-2.6.33.5-120.rt23.1.fc13.ccrma.i686
kernel-rt-devel-2.6.33.5-120.rt23.1.fc13.ccrma.i686
but i can't seem to find a kernel-headers package to match this realtime kernel... meanwhile having
kernel-headers-2.6.33.6-147.fc13.i686
covers gcc dependencies... is this even acceptable?! ...recommendations?
