I don't have the full dmesg (that was an except from my IRC logs) but I've confirmed it was FreeBSD 8.2-STABLE.

Since you've clarified that the current driver only sends TRIM commands if the device advertises TRIM support, I withdraw my concerns. --=20 Peter Jeremy --FsscpQKzF/jJk6ya Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJUfs9rXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRFRUIyOTg2QzMwNjcxRTc0RTY1QzIyN0Ux NkE1OTdBMEU0QTIwQjM0AAoJEBall6Dkogs0DJcP/ikspGkeSiETAjN+jYAFOnPu JTD7IPPwRk0QKPDmDaZzdGz82hNJMVWX6esuhQBi1musQ9eDCePaKfy52R2Vr2A5 sXVgQNGwj4bj6rIWA12Mwldy5uDjcmccRprn3U1bA7d2DcxjXPD8eL2tu/dV+C0U +2m1xgPXvxbjIcsgFxnFPttdSSezuaBmu4vm6UK63gUh6hXdwyYM9dGahlxXm8OO vLy5sG/C3hrFCijeGkpdXWYVhggr4/TVzm8dE9Z/ViFqHeGCXPP6k6ldJE9qlFTZ VWjYbwivK4zqGoE71z0ZEwqt0GSDg9qatNBIZIlJ4vizdpXayQ769YRP7X0jPPqb BTNDD78I0meHlfn0pqW2FoXG7YGu1285rYRa4VyZi1rfncTbn0M2ga2fyaiA4XoM 3LAg3B+5jlgI2FLpqMejrOIe5Xz2TLE9Cv9iTiyt5ZwJARhKH2Ejw/xnA1ygSZpw 7YZhbAe4iKBRJXDYMhUuzg+m/IGafwTMwg7gu2fPKGWNESmovei1DQXq0AIqpOeB M1d6X20ivo8ZVE2fRdVy7ffY7N8qgrjYjzDzRWcFVZPl0xFQICvJ5Lyj39xSVofY LvHUduGC4ezkmtQh6zSKaCyHHDCnWqzAbMU3XEpRIHfJZK3vs4d8tSJtDoAYk/D7 azVZ8UQWpgFg+TtBZZ59 =TxDg -----END PGP SIGNATURE----- --FsscpQKzF/jJk6ya--
