The system has a little memory left, then reboot it, and get the panic.
Perhaps this is a bug and trigger it like this and the latest kernel maybe
also have the problem.
use a lot of memory
wake up kswapd()
reclaim some pages from init thread (pid=1)
reboot
shutdown the disk
init thread read data from disk
page fault, because the page has already reclaimed
receive SIGBUS, and init thread exit
trigger the panic
Thanks,
