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.
