I had the (probably) same problem with a Crucial SSD with old firmware. With my problem, the mps driver or mpslsi driver logs the timeouts rather than AHCI. With new disk firmware, it works fine so far (about 2-3 weeks). Here is my forum thread http://forums.freebsd.org/showthread.php?t=28252 I can cause a very similar error by hot pulling the disk. After putting the disk back in, I can't use the disk until rebooting. (And I reproduced the same problem with a Seagate Green spinning disk). After the firmware upgrade, this test passes, so I put it back to work in the machine. Here is a thread with a similar problem with an OCZ Vertex 3 http://forums.freebsd.org/showthread.php?t=27128 I didn't try "camcontrol rescan". But I tried "camcontrol reset ...." which caused a kernel panic (meaning FreeBSD is most likely at least partially to blame). ;) Peter On 02/01/2012 02:40 PM, Willem Jan Withagen wrote: > Hi, > > I have this ZFS server up for about 27 days, and about 3 weeks ago (was > not really paying attention) it turns out it lost its SSD that I'm using > for log and cache.
