Bug#625922: SATA devices get reset without real hardware failure
This is mostly a mee too to report that I have had this issue at least
three times in the past 4 months (more or less), and every time with the
one ST2000DL003-9VT166 drive in my computer (out of four). I'm also
running with the CC32 firmware (apparently there's nothing more recent)
but the Linux kernel is newer:
Linux version 3.2.0-2-amd64 (Debian 3.2.15-1)
(debian-kernel@lists.debian.org) (gcc version 4.6.3 (Debian 4.6.3-1) )
#1 SMP Sun Apr 15 16:47:38 UTC 2012
Other details that may be relevant:
* It's part of a software RAID1 device (which causes it to drop out
obviously).
* I did a long test with SeaTools and it passed.
Here's how it started last night:

In theory, theory and practice are the same, but in practice they're different.
