Confusion about none working Interrupt 2 on a ATMega644P/1284P

I get mixed results using the USBtinyISP with the 1284P. Sometimes it seems to work, but I usually get an error message as well. Others here have reported better results.

BUT that's with a 1284P, if you have a 644P I would definitely give it a try.
