We're using LVM volumes exported directly into the domUs like so: disk =[ 'phy:vg1/xencaker-56392,xvda,w', ... ] > Could you try the attached patch to see if it makes any difference? 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? -Chris -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
