I encounter the same BUG_ON several times,
rt6i_ref is 2;
rt6i_dst is 0::0
Here is an example trace:
[278451.384635] Kernel BUG at ffc000b60238
[278451.384641] Internal error: Oops - BUG: 0 [#1] PREEMPT SMP

Hi, all
I used kernel-3.4 and applied patch
"6e9e16e6143b72 ipv6: replacing a rt6_info needs to purge possible
propagated rt6_infos too",
I'm not sure which opertion triggered the BUG_ON, from vmcore, I got that
rt6i_ref's counter is 0x2 and rt6i_dst is ff02::02
Until now ,the BUG_ON
