Hello all, I'm running 2009.06 and I've got a "random" kernel panic

every time I start loading up the writes on at pool. Memory has
been
tested extensively and I'm relatively certain this is not a hardware
related issue. here is the panic:

"Random" panics are, unfortunately, mostly caused by bad hardware.
Do you have ECC memory in the system? Did you run memtest86 on your
system?
Casper,
I have run memtest86 on the machine for about 4 hours which was enough
time to complete two passes. It is not ECC memory in this machine.
Perhaps if I said this isn't a random panic but more of an easily
reproducable panic... :) If I do dd if=/dev/zero of=/pool/blah
bs=1024k count=10000 it will always panic and reboot. In this type of
a scenario it seems less like hardware to me and more like a bug.
What do you think?
Brandon,
It looks like you have some bad RAM. The bad address
(ff7fff02fe41cc78)
appears to have a single-bit error (the leading ff7 should probably be
fff).
