    SubjectProfiling linux kernel.
    I am trying to profile the linux kernel. I booted the kernel with
    "profile=2" command line option and I am reading the /proc/profile using
    the readprofile command. The result I couldn't quite understand the
    result I got. The result shows that the kernel is spending a lot of time
    the machine_retstart function. One would normally think that the machine
    restart function is only invoked once.
    The kernel version I am using is 2.4.9-21 on an i386 platform.
    Any help in understanding the issue is appreciated.
