Bug #2971: kernel 4.7: buildworld causes panic: Bad link elm 0xffffffe1c766d500 prev->next != elm

----------------------------------------
The panic happened while doing buildworld. I am not entirely sure that the panic is not caused by a hardware error since prior to the panic two CRC errors showed up in /var/log/messages. On the other hand, it seems they might not be caused by a hardware error since prior to the panic I had seen CRC errors a couple of times and reinstalling the system got rid of them. In more detail, the machine has gone the following cycle of couple of times: 

1 - system has a panic (related to the kernel module I'm developing)
2 - hammer checkmap starts reporting errors occasionally
3 - then CRC errors show up /var/log/messages
4 - re-install the system and all errors vanish
5 - go back to 1

However, the last time after step 3 "make buildworld" led to this panic.
