I'm afraid I might be generating noise here. After my initial post I
found that I cannot trigger a panic without the latest changes to the
aoe driver in place. I haven't been able to trigger a panic using the
aoe driver inside 2.6.16.11.
I think we've identified the problem in the aoe driver, but if I'm
wrong, I will certainly try the TG3_FLAG_MBOX_WRITE_REORDER patch you
mention.
