To quote from your previous email:
yaffs_get_inode for object 146776
yaffs_read_inode for 146776

Now what is odd to me is that the object being referred to is supposed to be 
the root object (with an objectId of YAFFS_OBJECTID_ROOT which is 1).

Big question: Why is the object Id 146776?

Are you able to debug a bit more?
 The root object is dev->rootDir and dev->rootDir->objectId should be set up 
during yaffs_GutsInitialise().

Perhaps yaffs_GutsInitialise() is failing and returning early and the failure 
is not being handled correctly.

Could you try doing some tracing in yaffs_GutsInitialise()?

Thanx
