The problem is why d= oes the filesystem get corrupted? The OP says he can corrupt the filesyste= m on demand after a newfs. So it could be the Areca driver, or even bad ha= rdware. 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.
