Comment 570 for bug 620074

There are probably different bugs at stake here, and investigating one doesn't mean denying the other. Please be more respectful of people that try to improve our understanding of the problem instead of ranting.

Just a guess: ntfs-3g driver is using FUSE, while ext3 driver is in kernelspace. *Maybe* this can explain the difference (ntfs-3g isn't considered as in-kernel as regards I/O scheduling).
