Comment 151 for bug 620074

Maybe it's not only the preemption and the frequency. I think one of these things could be:

General setup:
- Control Group support DISABLED
- Group CPU Scheduler DISABLED
- Enable full-sized data structures for core ENABLED
- Enable futex support ENABLED
- Use full shmem filesystem ENABLED
- Enable AIO support ENABLED
- SLAB Allocator: SLUB

Processor type and features (ENABLED):
- Tickless System (NO_HZ)
- High Resolution Timer Support
- HPET Timer Support
- Multi-core scheduler support
- Preemptible RCU
- 64 bit Memory and IO resources
- Add LRU list to track non-evictable pages

Good luck...
