- do you get any output on serial console?
- maybe post codes are sent to LPC instead of PCI? There's usually some
register to change that.

Hi,

Please post output of superio tool in verbose mode. Maybe you need to set input 
to the ITE if it is 48Mhz or 24Mhz, usually it is some bit in CR20-2f

I dont have any POST card so i  dont know how the IO is routed.

Also provide lspci -vvvxxx

Check if your image contains following at the end:

I didn't see such struct in my image,so maybe it's related to IRQ 
routing??

It is the ROMSTRAP for HT setup. I think this is the reason why it does not 
work. If you build image for M2V-MX SE you should see it at the end of the image 
(same counts for A8V-E SE).
