Comment 8 for bug 208551

I'm having the same issue pointed to in the thread mentioned above:
http://www.issociate.de/board/post/471929/2.6.24-rc6_reproducible_raid5_hang.html

It seems that this was fixed in kernel version 2.6.25. Would it be possible to backport this to ubuntu kernels? It's basically impossible to use XFS on SW raid without it:

At least, it's impossible when dealing with multi terabyte raid5 arrays, which I don't think are particularly uncommon at this point.
