I see this with Ubuntu saucy (Kernel 3.11.0-12-generic 64 bit.), on a
Thinkpad T520 as well. This seems to happen when the system is under
heavy workload and I experience system freezes at the same time (So it
does seem to have a usability impact for me).

Title:
SATA link frequently resetting
Status in “linux” package in Ubuntu:
Invalid
Bug description:
I installed Ubuntu 11.10 on a brand-new Lenovo Thinkpad T520. I can
use the system without notable problem (though I have not run any
performance tests yet), however the kernel frequently (every few
seconds) writes the following error messages to /var/log/syslog:
.....

Again, the system is brand-new and hence I guess that this is no
hardware problem. Searching the web I found that someone else with a
T520 has a similar problem:

Thank you very much in advance!
