Interesting. Sounds like a race between writing back the inode and
it being freed. How long does it take to reproduce the problem?
Do you have a script that you could share?

Next question - what is the setting of ikeep/noikeep in your mount
options? If you dump /proc/self/mounts on 2.6.28 it will tell us
if inode clusters are being deleted or not....

Cheers,

Dave.
