Oh yea, the vDSO stuff slipped in after I last tested the ppc64 bits, so I wouldn't be surprised if that's broken. For now I'm just disabling the vsyscall/fsyscall/vDSO bits on the arches that support it until I get a generic interface setup that would allow it to be consistent with the new time infrastructure. Hopefully I'll have that done (I'm targeting x86-64 atleast) by the next release.
