We do that in our office @work. Perhaps this will help:

If false, the ctime differences between the index and the working tree
are ignored; useful when the inode change time is regularly modified
by something outside Git (file system crawlers and some backup
systems). See git-update-index(1). True by default."

(Quoted via http://git-scm.com/docs/git-config )

When/if I have problems I set that false.
