I'm experiencing TCP related oopses with this kernel (not seen in -mm4), 
.config file attached.

Here are two backtraces, the first happened a few seconds after logging 
in via ssh, the second happened soon after boot (using selinux=0, just to 
make sure).

Oops #1:
-----------

I think I fixed this one yesterday.  Callers of tcp_fragment()
in tcp_output.c were not accounting packets correctly.  I
believe this is what will fix it, and this is in Linus's

(either that or some other card whose driver
enables TSO by default)
