Problem with TCP/IP stack?

[Tarc]

I found in dmesg following lines:

 tcp_sack_output: Computed sack_bytes_retransmitted (1400) not the same as cached value (2800)
 

This problems founded after latest recompilling & reinstalling kernel.

My dmesg can be found at http://tarc.po.cs.msu.su/usr/tarc/kernels/current/dmesg
Kernel config at http://tarc.po.cs.msu.su/usr/tarc/kernels/TarcCurrent
What shall I do in this case?
