I'm trying to port coreboot to the gigabyte ga-945gcm-s2l, which has a
945gc northbridge, a ich7 southbridge and a ite it8718f sio. I'm trying
all this with a 1067fsb cpu, so in that last aspect there is no
precedent in coreboot.

I encountered some raminit issues where the MCHBAR(CLKCFG) was
incorrectly written, but this was fixed in

Right now I'm stuck in smm_init in southbridge/intel/i82801gx/smi.c.
The boot process completely hangs when wbinvd() is called which supposed
to "Write Back and Invalidate Cache" according to

What does this mean? Did the raminit not work?

Kind regards
