Meh .. what backend are you using?  We're using LVM volumes exported 
directly into the domUs like so:

disk =[ 'phy:vg1/xencaker-56392,xvda,w', ... ]

Unfortunately we're still in the same place... pv_ops kernels are still 
hanging after heavy disk IO:

works - 2.6.18.x (from xen-unstable)
hangs - 2.6.25-rc3-git3
hangs - 2.6.25-rc3-git3 + your patch

Any other suggestions or debugging I can provide that would be useful to 
squash this?
