I mostly notice it after a power on as I usually power off after 
reflashing the ROM. Once it hangs a reset will sometimes start it. Other 
times I can sit there reseting it for quite a few attempts without luck, 
at which point I usually reboot with the original BIOS.

 From the output it appears to be sticking in ram initialisation, 
possibly reading the SPD info, however all of the SMBus functions appear 
to have timeouts so I don't think it should hang, unless they are not 
working properly. Of course the hang may just be coincidental with the 
SPD stuff and have nothing at all to do with it.

It didn't appear to. I did still get some hangs. Often just changing a 
single line of code may make things better or worse, however the hang 
always seems to happen at 1 of 2 points.

Does ROMCC warn if it runs out of registers ?

I have the standard EPIA  vt8601 NB, vt8623 SB.

How do I go about getting that info ?
