I just encountered this problem with 12.1 also on a 2600. The way I got it to work was by setting the "TFTP_CHECKSUM" variable (I think that's what it is called) to the value of 0. It worked after this.

I reported it to Cisco and posted something on the list here a month or two back. There is a bug in some of the 12.1 codes.
