 Doug, does your kernel have TCP_SIGNATURE option?  The patch[*] for
 net/openbgpd can be used as a workaround if it was due to TCP_MD5SIG
 option on the listening sockets.

 While this is an ugly hack and I will investigate more reasonable
 solution for that, I want to narrow down the cause first.  Can anyone
 who are using a 8-STABLE kenrel with TCP_SIGNATURE let me know if
 this works or not?
