I don't know what this could be, but have you tried turning on the various GIT_TRACE env variables document in "man git"? Some of those might hold a clue to what's going on here. Have you tried to do other git-independent tests to see if in general the NFS failover isn't resulting in data being written as applications expect? E.g. doing a recursive wget of some data with known SHA1-sums, or doing a stess test of some sort on a filesystem that uses checksums (such as btrfs), which could be loop-mounted to a file stored on NFS.
