Same here, thanks for the log though :) Your flash controller seems
pretty unlocked. That feeds my suspicion that it's not the controller's
state that is causing trouble. I guess, I have to go back to the data-
sheet.

Btw, flashrom has an option `-o logfile` that makes it easier to catch
the output (e.g. you never miss the stderr messages).

Nico
