it is not listed as unknown, but it is not detected (apparently).
actually the chip has been marked as fully tested in 0.9.6 due to this

from what you write i would assume that you have a bad connection
between the programmer and the chip and it does only work by "accident"
sometimes. if you believe otherwise please send a verbose log.
