Yes. In my case, the problem turned out to be a marginal SATA-III port on =
the motherboard which was determined after swapping SSDs, SATA cables, etce=
tera to finally pin down the problem. When trouble-shooting this issue, I =
recall googling a particular missive by Alexander Motion in which he indica=
tes these problems are potentially due to any number of hardware-related re=
asons hence the exhaustive search for the culprit which, as he suggested, d=
id indeed turn out to be the hardware. It's actually rather interesting =
how borderline hardware can be - the port in question could handle an Intel=
510 SSD running at full SATA-III speed but an Intel 520 pushed it over the=
brink.

Did you get anywhere with this?
Seeing a similar thing on some new Patsburg based machines with KINGSTON SS=

Subject: AHCI Timeouts on SATA III with Intel 520 SSDs
I've got a couple of Intel 520 SSDs that I'm running on an Intel Sandy-brid=
ge based system(Core i5-2500K H67 chipset).
Unfortunately, the drives experience AHCI Timeouts when connected to the SA=
TA III ports. If, however, I connect the drives to the
SATA-II ports on the same system the drives do not timeout. NCQ is enabled=
. Below is the complete dmesg showing the issue. For
my testing, I'm just using a FreeBSD 9.0 Release (amd64) generic kernel usi=
ng 'dd if=3D/dev/ada0 of=3D/dev/null bs=3D1m' to exhibit the
behavior. The drives, ofcourse, are brand new and again if I run them off =
the SATA-II ports instead of the SATA-III ports the
problem goes away but then so does the performance.
Suggestions?
