I do not see any problems with the disassembled code from my limited x86-64 ASM
knowledge.

There're only two entries that will run to ffffffff80b10416, one is
> ffffffff80b103a0: 48 85 f6              testq   %rsi, %rsi
> ffffffff80b103a3: 75 64                 jne     0xffffffff80b10409 <in6_selecthlim+0x89>

, the another one is
> ffffffff80b103fe: 48 8b 78 20           movq    0x20(%rax), %rdi
> ffffffff80b10402: eb 08                 jmp     0xffffffff80b1040c <in6_selecthlim+0x8c>

So I suspect the line number 850 by kgdb is wrong, and the correct one should
be 861.

I have no evidences but may you please have a try with the patch ?
