:I have no idea what AIO is. And yes I was and am using SMB.
    Excellent, then I've found the problem.  SMB is terminating its 
    'kthread' (which is a bastardized FreeBSD-compatible proc+thread
    combo) without cleaning up the process structure, and that is causing
    the panic.
    I'm working on a patch now.
