    What about the swap file?
    i.e. the Oops is dumped to the first (after the header) sector of the
    swap file. The computer is restarted automatically. I don't
    think that it a good idea to continue after an Oops:
    if you kill a kernel thread, then you have memory corruptions,
    lost spinlocks, lost semaphores: the computer will crash in a few
    seconds anyway.

    sys_swapoff() clears the first data sector,
    sys_swapon() checks if the swap partition contains a oops, and if there
    is an oops it transfers the oops into the system log, and then
    clears the first sector.

    AFAIK, this is would similar to the NT implemenation: if you have
    no swap file, then the system cannot dump BSOD's.


    Regards,
    Manfred
