It'll be hard to say until this change gets through the Xen push gate
and that version gets used for other branches (linux testing, libvirt,
ovmf, osstest's own gate etc).
At the moment it looks like it has helped with some but not all of the
issues.
These:
http://logs.test-lab.xenproject.org/osstest/results/host/merlot0.html
http://logs.test-lab.xenproject.org/osstest/results/host/merlot1.html
still don't look brilliant, even if you only pay attention to the
xen-unstable lines.
Ian.
