Anyone know the status of all the Epia's working with V2?

I have the plain old VIA EPIA (800/5000) working a good 80 % of the time.

Not sure if my problems are buggy northbridge setup or buggy motherboard - it
generates some spurious serial at power on, and sometimes hangs reading the
smbus to size the ram.

CVS is upto date with my current northbridge code, but not my clean up of the
southbridge code.

The spurious serial at power on. (Assuming it is just a character) sounds like
normal line noise.

As for smbus they seem to be the most common board problem I have seen.  Last
time I trace one down it really was a board design defect, and made using lmsensors
on that board impossible.  In any event it is not terribly hard to put
in timeouts and board resets to get past smbus problems.

Although if you are having problems 20% of the time that is much more often then I
have seen problems on other boards.  Usually I see problems closer to the 1% mark.

Unfortunately not, it's more like a couple of dozen characters, which if the
reset button is pressed, come out as text from LB. I'm assuming that the
spurious characters are because the serial UART is not setup the first time
power is applied, but is still configured when the reset button get's pressed.

The 20% is just an estimate, it could well be more or less than this. I could
have been miss lead as to the smbus as well, i'm basing this assumption on the
fact it always seems to hang when reading the SDRAM config registers for the
first memory bank.

for our tuturoials we found the EPIAs with linuxbios to boot 100% of the 
time, and this was several dozen of them.

Hmmm, guess this means I have a problem here....
Was that V1 or V2 ? I don't remember having problems with V1 code.
What version of gcc etc did you use/are you using ?
