    Hmm.  post your 'dmesg' output.  Also, if you are running HEAD rather
    then DragonFly_Stable, or if you are running a GCC-3.4 built kernel,
    I recommend going back to a standard DragonFly_Stable/gcc-2 built kernel.
    We need to rule-out as many possible sources to the problem as possible.

    It would even be worthwhile to try some of the older stable kernels, which
    you can find on the snapshots site (just the kernels, not the whole ISO),
    to see if the kernel had the problem prior to e.g. 2 months ago.

    I have *never* seen that panic before so its either something that occured
    very recently, or some weird set of build circumstances, or something 
    related to how the hardware interacts with the kernel.
