Dear Everyone,
I am seeing the following my system log on my 5 month old Lenovo T520,
which has an OCZ Vertex 3 with the 2.15 firmware from OCZ:

Whenever this happens, KDE becomes semi-unresponsive. My first thought
was that this might be an indicator that the Intel Cougar Point
chipset in my laptop is dying, but I did a quick google search and
people seemed to think it was a kernel bug. The last time I called
Lenovo about an issue I had encountered, they told me that unless they
can reproduce it on Windows, they would not do anything. Does it look
like a hardware problem or a kernel bug? I want the opinion of someone
here before I call Lenovo about it.
Yours truly,
Richard Yao

That sounds like a hardware problem, but it could be either the laptop
or the drive - it appears that the SATA link is going down (the Serror
indicates a CommWake and device exchanged).

Same problem here with same hardware and KDE. I opened a bug report here
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1247806. Any news about it
