I managed to merge the UBI/UBIFS specific code from the link you gave me (I took the latest and greatest) and I have a kernel that now compiles successfully.

If you have any ideas on this it would be great - right now I will be researching if our hypothesis is true and how to resolve it.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>Thanks Dave<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
