This is curious. I was trying really hard even on a similar machine (well, about half of your size) but no luck with reproducing the warning you see. OTOH I was getting a *flood* of warnings from ext4_da_update_reserve_space() - I've fixed that up and posted patch to linux-ext4 (ext4: Fix warning in ext4_da_update_reserve_space()).
