Well, almost. They gripe when rebooting, but I haven't seen one other than that. This is 3.6.11-rt23 on a 64 core DL980 I set up to run some latency tests on.

Don't suppose you know why LAZY_PREEMPT would make 3.0-rt explode if you turn on wakeup_rt tracer do you? I backported that and your softirq changes to 3.0. New softirq handling scheme work spiffy there, LAZY_PREEMPT works fine too.. until you turn tracing on, then it corrupts memory, and makes mushroom cloud. -Mike
