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
