    Kernel Debugger + serial console.
    ftp://oss.sgi.com/projects/kdb/download/ix86/. man Documentation/kdb.mm.

    Make sure that you enable the NMI watchdog, boot 2.4.x kernels with
    "nmi_watchdog=1". Unless the problem is a total hardware lockup, nmi
    will trip after 5 seconds and drop into kdb.
