I got a problem regarding tty with today's tree.
When re-starting X, it complains that it cannot change to VT7.
Via strace, 

  open("/dev/tty0", O_WRONLY)             = 7
  ioctl(7, VIDIOC_QUERYCAP or VT_OPENQRY, 0x81e80c4) = 0
  close(7)                                = 0
  write(0, "(--) using VT number 7\n\n", 24) = 24
  getppid()                               = 3240
  getpgid(0xca8)                          = 3240
  setpgid(0, 3240)                        = 0
  setsid()                                = 3241
  open("/dev/vc/7", O_RDWR|O_NONBLOCK)    = -1 ENOENT (No such file or directory)
  open("/dev/tty7", O_RDWR|O_NONBLOCK)    = -1 EIO (Input/output error)
  write(2, "\nFatal server error:\n", 21) = 21

A similar error can be seen at shutdown, complains about the tty error
and the halt process hangs up.

Unfortunately it's hard to bisect since Aug 11 and Aug 12 trees don't
boot, and Aug 8 tree has a problem regarding cred...


thanks,

Takashi
