This is probably a result of a percpu_counter bug in an IPv6 patch. As a 
temporary measure you can disable IPv6 (if you don't need it), eg. as 
suggested at http://fedorasolved.org/network-solutions/disable-ipv6

It was patched after rc1 
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6-stable.git;a=commit;h=41bb78b4b9adb21cf2c395b6b880aaae99c788b7
so should be fixed when I next do a build of 2.6.37 .
