%rax contains 0x656b736968772d31
In my x86_64 it is obtained from %rbx, which seems to be correct, so I'm
a bit stuck, something has rewritten internals of the socket structure,
and it does not look like free poisoning.
0xffffffff8024ea14 <netlink_broadcast+289>: mov 0x268(%rbx),%rax
0xffffffff8024ea1b <netlink_broadcast+296>: bt %r15d,(%rax)
Can you describe your load? Is it too high to put a debug printk there?
Can you enable as much debug options as possible?
