Okay AEABI led me a merry dance, had to install a new tool chain.  Good for
the soul I guess.  Anyway the problem persists with either ABI.  Now testing
with the 2.6.34 stable source.

I'm not using the balloon board code, although at some point I'll have to
support the 2.05g.  I've looked at the balloonboard patches and can see nothing
significantly different apart from I have NFS disabled.

Yep older CVS yaffs works with 2.6.33 it's just 2.6.34 that looks broke to me.


Anyway I have a patch that works for me by deleting a couple of kfree()s and
corresponding yaffs_CloneString()s, but clearly they must have been there for
some purpose.  So can anyone tell me why this patch is bad, or how some builds
work without it ?
