    Hi

    Within one hour I got the next one, kdb log in attachment.

    first line of kdb_log:

    ------------------------------------------------

    Entering kdb (current=0xc2168000, pid 1593) kdb: Debugger re-entered on cpu 1, new reason = 10

    Unknown kdb command: 'o2o6o8o'

    *** input to kdb ^^^^^^^ is rubbish because something felt on keyboard...

    ------------------------------------------------------------------------

    Observations:
    - compiling the kernel as UP keeps it from crashing
    - the bios RTC is most of the times disturbed after a crash

    The application 'hart' does basically the following:


    for(;;)
    {
    open port (ttyS0)
    write a few bytes
    ioctl toggle RTS line
    read a few bytes (with poll)
    close port
    }

    If some information is required, I'll try to provide it.
