In trying to sample kernel_task, I'm told I don't have rights to do
such. I've tried using sudo sample, but still cannot sample it.
I don't believe that you can 'sample' the kernel because the
kernel_task is, well, in the kernel. I think you'll need to figure
out another approach ('sample' and friends assume that you are
dealing with a user-mode executable, I think).
Is the project a kernel extension?
Does the Activity Monitor CPU meter show that the CPU is red-lined?
Are you thrashing?
Can you ping the system, or log in remotely from another system?
