Hi, A previously working system started to show problems with the tape drive since doing a make world. The may23 kernel worked great, but my Friday the 13th kernel is giving me problems on doing a backup. (yes, I was tempting fate! ;-)) The MFC seems to be from the 24th of June, so I doubt its an all pervasive bug. Is it just coincidence that my hardware is going bad ?
