After additional hint from Thomas Osterried I can confirm that the problem 
I have been dealing with for half of a year comes from continuous dirty 
pages increas:

http://bugzilla.kernel.org/attachment.cgi?id=13864&action=view (in 1 KB 
units)

So, after two days of uptime I have ~140MB of dirty pages and that 
explains why my system crashes every 2-3 weeks.
