does the filesystem get corrupted? The OP says he can corrupt the filesystem on
demand after a newfs. So it could be the Areca driver, or even bad hardware.
My point is that this panic can happen when your filesystem becomes
corrupted, and the panic keeps happening during "normal" filesystem
operations until you forcibly fsck it, at which point the panic goes
away.
