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', ... ]
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?
Are you running an SMP or UP domain? I found I could get hangs very
easily with UP (but I need confirm it isn't a result of some other very
experimental patches).
