Hello Vladimir,

Yes, We have run memtest in our system. It's very seldom to find a system with 
a hardware memory problem running. When we find a memory problem the kernel 
doesn't boot. I am going to pass memtest in some of the system with reiserfs 
corruption problem.

Could I give you more information? Perhaps if I run 'reiserfsck 
--rebuild-tree' and I give you the traces... would it be useful?

Regards,

Paco
