Well, adding symbols didn't add line numbers to the backtrace. But now I
can use addr2line with the vmlinux (all 78mb of it) to get you guys a
backtrace with line numbers :)


So,

OOPS (NULL pointer deference) at

  drivers/char/tty_io.c:1321  (tty_open)

Backtrace,

  fs/char_dev.c:397 (chrdev_open)
  fs/char_dev.c:357 (chrdev_open)
  fs/open.c:841     (__dentry_open)
  arch/x86/include/asm/atomic_64.h:117 (do_flip_open)
  fs/file.c:459     (alloc_fd)
  ...
