Yes i'm sure. I was actually debugging some kernel pebs code,
and had a heavily instrumented pebs code path and was first trying
to figure out what went wrong in the kernel, until I realized 
that the userland was broken.

Does :p work for anyone else?

BTW I hope the perf userland becomes more stable again. Recently I've had
far more trouble with the user binary than the kernel driver, which
is unusal.
