AVRISP mkII programming of Arduino BT

I've got 2 arduino bt-v06's I'm trying to program with an AVRISP MKII. They both give the same error:

avrdude: stk500v2_command(): command failed
avrdude: stk500v2_program_enable(): bad AVRISPmkII connection status: MOSI fail, SCK fail
avrdude: initialization failed, rc=-1

Is this a known and/or repairable issue?

I was able to successfully burn a bootloader to several Diecimilas, a Duemilanove, and one identical Arduino BT, so I think that rules out a problem with the AVRISP MKII.

I also tried with AVR Studio 4 and 5, but got the same or similar errors.
