I must say that I have had only good experiences with Avrdude hitherto, and am very happy that I can use the Jtagice under Linux.
Well, about my CAN128 mishap: All went fine for, say 25, programming cycles. Then I observed that the processor was not reset after programming, I had to do that manually to get the program going. Then after yet another dozens of programmings I had no more access to the chip. Avrdude suggests that the JTAG fuse is not enabled. The program ran though. Till now I programmed under Linux, Avrdude version 5.0. I then tried to get contact using Avr studio unde Windows, but with no success. I cut out the chip and soldered in a new one. The first or second time I programmed I got the same problem with the new chip. Now I cut out the chip again and soldered a Mega128 in its place. I have now programmed under Linux with the same setup several dozen times without any problem. I'm afraid I can't supply more details to help you, althouhg I quite understand your problem with finding such spurious errors.
