[1.] One line summary of the problem: using dd on a broken hdd causes kernel NULL pointer dereference [2.] Full description of the problem/report: I have a broken hdd (unreadable sector). While dd-ing it into another same size hdd, I get kernel-level error. First time it is a NULL pointer dereference then a few minutes later its a BUG in mm/slab.c, no IO operation anymore shown by iostat, and dd gets kernel-space process (shown as [dd] by ps). System becomes unstable, processes get segfaulted, even reboot is unoperational.
