Hi,
I have recently upgraded from 4.1.6 to 4.2.1 and am now seeing a kernel panic when trying to do IPSec (using ipsec-tools, racoon and setkey) over IPv6:
Call Trace: [<ffffffff8151460c>] ? ip6_dst_destroy+0x5c/0xf0 [<ffffffff8146343f>] dst_destroy+0x6f/0xd0 [<ffffffff81463557>] dst_gc_task+0xb7/0x220 [<ffffffff8100cd13>] ? __switch_to+0x273/0x480 [<ffffffff8106dd21>] process_on_work+0x141/0340 [<ffffffff8106df93>] worker_thread+0x73/0x470 [<ffffffff8106df20>] ? process_on_work+0x340/0x340 [<ffffffff8106df20>] ? process_on_work+0x340/0x340 [<ffffffff81073645>] kthread+0xe5/0x100 [<ffffffff81073560>] ? kthread_create_on_node+0x180/0x180 [<ffffffff8156059f>] ret_from_fork+0x3f/0x70 [<ffffffff81073560>] ? kthread_create_on_node+0x180/0x180

(I had to copy this by hand from the console, so there may be typos, sorry)
I have done a git bisect on the kernel and found that this started to occur at 8d0b94afdca84598912347e61defa846a0988d04, if I revert this change in kernel 4.2.2, then the system works as expected.
Is this the right place to report this, has it been seen before ?
I'm not on the mailing list so please CC me in responses.
