Raptor has kindly given me access to a Talos II so i can do dev work and also test patches there if needed. a couple of other things i think are important: - non-OpenFirmware ppc64le loader - i see a couple of people have already mentioned this. - SMP performance is quite bad; this 44-core SMT4 Talos II runs buildworld at the same speed as my 8-core 2.6GHz Xeon system. i mentioned this to Justin and he suspects this could be from locking issues in vm/pmap.
