Boot with 2.6.32 and see if the per cpu allocator works. Check if there are any changes to memory consumption. Create a few thousand virtual ethernet devices and see if the system keels over. It may also be good to run some scheduler test. Compare AIM9 of latest SLES with 2.6.32. Concurrent page fault test? Then a performance test with lots of concurrency but the usual stuff wont work since HPC apps usually pin. Run latencytest (available in the lldiag package) from kernel.org/pub/linux/kernel/people/christoph/lldiag and see how the disturbances by the OS are changed. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
