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. I agree that is old but my point was that there are SSDs around that can't cope with TRIM. 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--
