Unfortunately, not all patches can be disabled without breaking the build. The latencies look normal when I disable these two patches: rt-time-starvation-fix.patch rt-time-starvation-fix-update.patch Throwing in the versions from 2.6.23.3-rt5 doesn't help, the effect stays the same. So I assume it is a side effect.
