i've uploaded my current tree (-V0.7.41-01) to:
http://redhat.com/~mingo/realtime-preempt/
it includes the latest round of RCU fixes - but doesnt solve the SMP bootup crash.

With this kernel I can run for some 20 minutes, then the ip_dst_cache overflows.
I gather it has something to do with RCU...
If I just let it run and grep ip_dst_cache /proc/slab it goes up to 4096 (max) and then the printk's are starting, and the networks stops.
After i up the limit to the double (echo "8192" > /proc/sys/net/ipv4/route/max_size) network starts to work again.
But of course, after a while it overflows again:
# grep ip_dst_cache /proc/slabinfo
ip_dst_cache 8192 8205 256 15 1 : tunables 16 8 0 : slabdata 547 547 0
I haven't tried the vanilla 2.6.12-rc2 kernel, and I don't have the time to do that right now, but i figured it would have something to do with your patch. Older 2.6.8 works just fine.
