It could be.

That's something along the lines with what Vojtech Pavlik suggested[1]:

     This looks seriously like uninitialized memory (12-bit FAT
     perhaps?) - and very much like a Qemu bug. It doesn't even make
     sense if interpreted as keyboard scancodes - 00 is reserved and ff
     is an error condition.
