 | Compiling TCP_CHECKSUM into kernel, and starting a checksum-enabled TCP session (bgpd from quagga) panics kernel. It's 100% reproducible for me.

 You mean TCP_SIGNATURE? This was fixed in:
 
 revision 1.178
 date: 2014-10-25 11:07:13 -0400;  author: christos;  state: Exp;  lines: +30 -25;  commitid: ihyehwegSyD1TAVx;
 Avoid stack overflow when SACK and TCP_SIGNATURE are both present. Thanks
 to Jonathan Looney for pointing this out.
