Hi all, Does anyone have any experience with applying Ingo Molnar's realtime-preempt patch to recent FC4 kernels like 2.6.14-1.1633 in Testing? I tried sticking patch-2.6.14-rt2 in the srpm's kernel-2.6.spec as patch101 but that made patch810, patch812, patch1013, patch1083, patch1500-1505 fail. So I commented them out. Then the build process continued only to stop with make[1]: *** [nonint_oldconfig] Error 12 I really have no idea if this is possible at all or that I better should use a plain vanilla kernel so any pointers appreciated. The patch can be found at people.redhat.com/mingo/realtime-preempt/ Thanks and regards, Patrick
