This prompt is xmon (CONFIG_XMON), the kernel debugger. It can be used
to trace kernel bugs, it doesn't use standard readline commands (^c etc)
but it's own internal commands (most of which may not be of use to you).
Though in this case "x" (exit) may have got you out and, assuming the
kernel didn't oops, you may have been able to unmount filesystems and
reboot.

Here are the commands available within xmon:

  d     dump bytes
  di    dump instructions
  df    dump float values
  dd    dump double values
  e     print exception information
  h     dump hash table
  m     examine/change memory
  mm    move a block of memory
  ms    set a block of memory
  md    compare two blocks of memory
  M     print System.map
  r     print registers
  S     print special registers
  t     print backtrace
  la    lookup address in system.map
  ls    lookup symbol in system.map
  x     exit monitor
