--y0ulUmNC+osPPQO6 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Several months ago, I added a OCZ Agility4 SSD to my 8.3 system. It had been running without problem but yesterday the system reported: Oct 28 08:54:36 server kernel: ahcich3: Timeout on slot 25 port 0 Oct 28 08:54:36 server kernel: ahcich3: is 00000000 cs 00000000 ss ffc1ffff= rs ffc1ffff tfd 50 serr 00000800 cmd 0004b017 Oct 28 08:57:40 server kernel: ahcich3: AHCI reset: device not ready after = 31000ms (tfd =3D 000000d0) Oct 28 08:57:40 server kernel: ahcich3: Timeout on slot 16 port 0 Oct 28 08:57:40 server kernel: ahcich3: is 00000000 cs 00010000 ss 00000000= rs 00010000 tfd d0 serr 00000000 cmd 0004b017 Oct 28 08:57:40 server kernel: ahcich3: AHCI reset: device not ready after = 31000ms (tfd =3D 000000d0) Oct 28 08:57:40 server kernel: ahcich3: Timeout on slot 16 port 0 Oct 28 08:57:40 server kernel: ahcich3: is 00000000 cs 00010000 ss 00000000= rs 00010000 tfd d0 serr 00000000 cmd 0004b017 Oct 28 08:57:40 server kernel: (ada6:ahcich3:0:0:0): lost device Oct 28 08:57:40 server kernel: ahcich3: AHCI reset: device not ready after = 31000ms (tfd =3D 000000d0) Oct 28 08:57:40 server kernel: ahcich3: Timeout on slot 16 port 0 Oct 28 08:57:40 server kernel: ahcich3: is 00000000 cs ffff07ff ss ffff07ff= rs ffff07ff tfd d0 serr 00000000 cmd 0004b017 Power-cycling the SSD recovered it and smartctl shows no problems. This makes me suspect it's an incompatibility between the SSD and the SATA controller or FreeBSD driver. The SSD is directly connected to a ATI IXP600 (one of the onboard ports on my Gigabyte GA-MA770-DS3) and is partitioned 3 ways: - a mirror in my ZFS root - ZIL for tha main data pool - L2ARC for tha main data pool Has anyone else seen this behaviour? The SSD firmware is currently 1.4.1.3 but the latest firmware on the OCZ site is 1.5.2 (though the release notes don't describe the differences). Has anyone tried either firmware version? --=20 Peter Jeremy --y0ulUmNC+osPPQO6 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAlCOXdEACgkQ/opHv/APuIc4HQCfRlHlUjG8AbNamjcQyCnJTIZj lUQAn2i2B/73KLP/NU/lasgZfyuZpNO1 =W5yL -----END PGP SIGNATURE----- --y0ulUmNC+osPPQO6--
