Try replacing module 02 by another one. (Block access in RAM and load from other device)

facepalm, yeah, i missed the power state. Status and error regs are off in pc3k when power is off, so they don't show sht without power, that's what disturbed me...

What error do you get (abrt, unc, idnf)?
not security locked?
