    [PATCH] pause_on_oops command line option · dd287796
    Andrew Morton 提交于
    Attempt to fix the problem wherein people's oops reports scroll off the screen
    due to repeated oopsing or to oopses on other CPUs.
    
    If this happens the user can reboot with the `pause_on_oops=<seconds>' option.
    It will allow the first oopsing CPU to print an oops record just a single
    time.  Second oopsing attempts, or oopses on other CPUs will cause those CPUs
    to enter a tight loop until the specified number of seconds have elapsed.
    
    The patch implements the infrastructure generically in the expectation that
    architectures other than x86 will find it useful.
