Do you think it is specific to the filesystem on raid-5? Have you tested
w/o md? I'd be a little surprised if the problem is at the raid layer (so
cc'ing the ext3/4 list), but maybe you tested that already.
Which arch is it, and which kernel? How big is the filesystem? With full
geometry information it might be easier for someone to reproduce & debug.
Thanks,

Marri, can you post your XOR driver the problem may be there.
Thanks,
