Miller [-- Attachment #1: Type: TEXT/PLAIN, Size: 5658 bytes --] 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).

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 tree already.
