    This one is slightly different:

    WARNING: at lib/list_debug.c:26 __list_add+0x61/0x90()
    list_add corruption. next->prev should be prev (c088e34c), but was
    00200200. (next=f7814774).

    ...followed by the "unable to handle kernel paging request" as in
    previous e-mail. The numbers 00100104 and 00200200 seem to appear all
    the time.

    At least it is 100% reproducible now and with nice oopses too :-)


    "The animistic metaphor of the bug that maliciously sneaked in while
    the programmer was not looking is intellectually dishonest as it
    disguises that the error is the programmer's own creation."
