A variation of this problem (evident on Intel chipsets and various SSDs) was solved for some cases here: http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/dev/ic/ahci.c.diff?r1=1.13&r2=1.14 That was based on Dragonfly's commit: http://gitweb.dragonflybsd.org/dragonfly.git/commitdiff/f2dba7003b2add226b3999a41a99fd278cc5a26f (which is a port of the OpenBSD ahci driver) Perhaps this is a long shot, but maybe your combination of controller and SSD require more time to sort out thier business. You could try editing /usr/src/sys/dev/ic/ahci.c to achieve this, change this is around line 1443: if (retries == 0) { retries = 1; goto retry; } to: if (retries <= 5) { retries++; goto retry; } Compile a new kernel, see if it helps?
