    Hello,

    I'm trying to use graid3 to create a raid volume from three
    250GB SATA discs. I can successfully label, format, and mount
    the disc. The problem arises when I try and migrate some data
    on to the new volume. I'm using rsync to do this from over the
    local network, unfortunately this seems to be produce an
    immediate and reproduceable panic (hand copied):

    Fatal trap 12: page fault while in kernel mode

    fault virtual address = 0xc30f8000
    fault code = supervisor write, page not present
    instruction pointer = 0x8:0xc05e9783
    stack pointer = 0x10:0xd8030c38
    frame pointer = 0x10:0xd8030c80
    code segment = base 0x0, limit 0xfffff type 0x1b
                 = DPL 0, pres 1, def32 1, gran 1
    processor eflags = interrupt enabled, resume, IOPL = 0
    current process = 617 (g_raid3 raid)
    trap number = 12
    panic: page fault

    Other programs (touch, ls, diskinfo, etc) do not seem to provoke
    the panic, but rsync will kill the system within a second.

    I got a dump (once), but I think it is corrupt in some way
    because I have not been able to get a backtrace or any other
    useful data from it.

    # kgdb kernel.debug /usr/crash/vmcore.0
    kgdb: kvm_read: invalid address (f9)

    (This line is printed again, and again, and again ...)

    This may be because I compiled my debugging kernel after I had
    installed the system, although it should have been an identical
    source tree ... I'm currently rebuilding the system to
    the freshest available -STABLE in the hope that may give a
    full backtrace.

    The only thing slightly odd about the machine is that each
    disc is one its own SATA controller. One disc is attached to an
    Intel ICH6 the other two are attached two Silicon Image (3112)
    based cards. The root device is ad2, since the additional cards
    have pushed themselves to the front. This is a temporary setup
    to facilitate migration of data from system to system.

    If I can do anything to help track the problem down, please say.
    I really want this to work, and I have some time in which to run
    tests.

    * A side note, I have noticed that the panic is often accompanied by
    a ATA DMA timeout (ad1). Could this cause the panic to occur?
