Well, can you run:

debugfs -R "stat <INO>" /dev/ROOT_DEV

on say, two or three of the inodes (replace INO with a number, and
ROOT_DEV with the root file system device) and send me the result?
That would be really helpful in understanding what might be going on.

Sure, I'll put together a more formal patch and do full QA run and
checking of the code paths, as a supposed a fairly superficial review
