Looking at the user manual, probably the only difference between the EPIA and EPIA V is that the EPIA has 2 IDE and no floppy where as the EPIA V loses 1 IDE for the floppy connector. Same chipsets. I am surprised it doesn't get further.
I get all of the "PCI: devfn 0x10, bad id 0xffffffff " on my EPIA. It certainly looks like something caused the board to reset though.
2 points.
The line that generates "0120d4 is the computed timing" doesnt actually set any timing values. I did have a look at it and I think some of the code is wrong. However I haven't removed it as I have found that the first SMBus read seems to fail and that is called from this routine.
Also where the output says "Slot 00 is SDRAM" is one of the few places that cause the system to hang. Maybe SMBus related, but I haven't proved that yet.
Markus, what ram are you using ? The reboot may well be due to the fact it hasn't been initialised properly. There have been problems with RAM and the EPIA Try enabling the RAM check in mainboard/auto.c and see if you get any errors before 0xa0000.
