small files seem to be ok. The smallest one for which I observed the 
problem was about 600MB. For the one of 6GB is always repeatable: cp 
folowed by cmp reports always differences in the files.

nothing relevant, the hard-disk does not seem to have bad sectors or 
something like that.

yes, reiserfs3. I use reiserfs 3.6.9 delivered with SuSE 9.0. Do you 
think a newer version would help? To me the problem seems to be in the 
kernel not in the utility programs.

Anyway is anybody interested in investigating this problem further? I 
can make a complete dump of the partition (it's about 80GB), such that 
it can be used in loop mode for test. I will also make some tests with 
the parition in the loop mode on another computer.

Otherwise I inted to reformat completely that partition (should I still 
use reiserfs3? somehow I don't trust it anymore).
