Please describe the problem.

"git status" returns a list of almost all files in the annex (located on a FAT32 device) with these messages:

git-annex: git status will show music/a.flac to be modified, since content availability has changed and git-annex was unable to update the index. This is only a cosmetic problem affecting git status; git add, git commit, etc won't be affected. To fix the git status display, you can run: git update-index -q --refresh music/a.flac
... (a lot of similar messages for +30000 files)

and then a new list of messages:

...
git-annex: thread blocked indefinitely in an MVar operation
error: external filter 'git-annex smudge --clean %f' failed 1
error: external filter 'git-annex smudge --clean %f' failed
git-annex: thread blocked indefinitely in an MVar operation

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
