Its either board-board instability due to small timing differences or the new input pins I guess.
Can you check the voltage on these pins on PBI? They should all be 5V, I'm wondering if some are not pulled up. I guess I need to double check I put the correct pin for them in the .qsf file too!
PBI_EXTSEL_N : IN STD_LOGIC;
PBI_MPD_N : IN STD_LOGIC;
PBI_REF_N : IN STD_LOGIC;
PBI_IRQ_N : IN STD_LOGIC;

Though thinking some more if you get 'no sync' then that is before all the new logic starts, so more likely the build-build instability on some boards only.

One thing to try, can you see if it's the same with a few different power supplies?

i did with same result, can anyone else confirm that core 9 works on on his v2 board?

Thanks for checking Nir. I guess it must be on the 'edge' and thus some boards work and not others. Its working well here, until I run Numen or try to use the internal freezer. They are real logic bugs though rather than a stability thing.
