Seems changing tags on both disks doesn't fix the issue: (ada0:ahcich0:0:0:0): Request requeued (ada0:ahcich0:0:0:0): Retrying command ahcich1: Timeout on slot 0 ahcich1: is 00000000 cs 00000001 ss 00000000 rs 00000001 tfd c0 serr 00000000 ahcich1: AHCI reset... ahcich1: SATA connect time=0ms status=00000123 ahcich1: ready wait time=18ms ahcich1: AHCI reset done: device found (ada1:ahcich1:0:0:0): Request requeued (ada1:ahcich1:0:0:0): Retrying command (ada1:ahcich1:0:0:0): Command timed out (ada1:ahcich1:0:0:0): Retrying command ahcich0: Timeout on slot 30 ahcich0: is 00000000 cs c0000000 ss 00000000 rs c0000000 tfd c0 serr 00000000 ahcich0: AHCI reset... ahcich0: SATA connect time=0ms status=00000123 ahcich0: ready wait time=18ms ahcich0: AHCI reset done: device found The only difference is that now i get "Request requeued" message. -- La prueba más fehaciente de que existe vida inteligente en otros planetas, es que no han intentado contactar con nosotros. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
