I am seeing a different problem which also bisects to this commit. There are
no kernel messages but ip6tables fails to run.

newton ~ # ip6tables -L -v
FATAL: Module ip6_tables not found.
ip6tables v1.4.3.1: can't initialize ip6tables table `filter': Memory allocation problem
Perhaps ip6tables or your kernel needs to be upgraded.

I get this error no matter which ip6tables sub-command I run. Ip6tables
is built into the kernel, not as modules.

An strace shows the failure to be 
socket(PF_INET6, SOCK_RAW, IPPROTO_RAW) = 3
getsockopt(3, SOL_IPV6, 0x40 /* IPV6_??? */, "filter\0\305\0w~\300\0wb\305P\24\312\t\0009b\305\216\23\0\0\310\341/g\16"..., [84]) = 0
brk(0)                                  = 0x8273000
brk(0x8294000)                          = 0x8294000
getsockopt(3, SOL_IPV6, 0x41 /* IPV6_??? */, 0x8273090, 0xbfd23628) = -1 ENOMEM (Cannot allocate memory)
close(3)                                = 0
