here 'is a loser' means: "tries to back up way too much stuff instead of
doing a nice incremental backup like it does on 2.6.20.4", correct?
since it appears to be caused by a kernel change, this is a serious

or library calls returns incorrect data?

maybe it's some sort of timestamp problem, on the FS level?
