Was this on resume from suspend/hibernate?
Comment 3 admin 2012-02-27 05:35:40 UTC 
No.
Has restarted system
Comment 4 Dave Jones 2012-02-27 15:43:07 UTC 
ffff8801e5761360 became a ffff880165761360  (e -> 6). A single bit got randomly flipped.
This is a sign of memory going bad, or some other hardware fault.
Comment 5 admin 2012-02-28 05:30:22 UTC 
With memory everything is all right. memtest some circles of tests have passed without errors. As tried to change memory modules. Results similar. At work with Windows any errors are absent.
