This just started happening to me. It's a striped non mirrored pool (I know I
know). A zfs scrub causes a panic under a minute. I can also trigger a panic by
doing tars etc. x86 64-bit kernel ... any ideas? Just to help rule out some
things, I changed the motherboard, memory and cpu and it still happens ... I
also think it happens on a 32-bit kernel.
