    Hi, I recently found a bug in the kernel. Information is included according 
    the suggested reporting format.

    The message the kernel gave:

    Code: 89 42 04 89 10 b8 01 00 00 00 c7 43 04 00 00 00 00 c7 03 00
    Aiee, killing interrupt handler
    Kernel panic: Attempted to kill the idle task!
    In interrupt handler - not syncing

    It also happened that it "Attempted to kill the init task!"


    1: Kernel panics on sending large ping packets using 'ping'

    2: When i try to send large ping packets, (i didnt try to find the underlimit)
    The kernel panics with an 'Aiee' message. This is reproducable.

    3: kernel, networking
