ubi image only mounts once

[Douglass, Woody]

Matt, 

Thanks for the quick reply. I have tried both ubiformat (passing -f with
my image) and nandwrite, both seem to behave the same way. The
filesystem mounts once, but when I reboot, it doesn't ever mount again.

I cannot upgrade my kernel as my development schedule is too aggressive;
I don't have time. I'm using 2.6.32 for now; if I fail at getting UBI to
work, I can fall back on jffs2, which works, but I prefer UBIFS.

Note that I did successfully load a ubi image with this kernel In the
past with a filesystem image generated from OpenEmbedded. Could my
mkfs.ubifs/ubinize be the issue?

Thanks,
Woody
