Re: [Xen-devel] xen.git branch reorg / crash with 2.6.30-rc3 pv_ops dom0

Interesting. Curiously its working for me on my machine, but has a tendency to crash a bit later with a protection fault on an RO page during memory allocation. I wonder if its related...

Certainly smells similar.

Yeah. The fault in both cases has an error-code of 3, so a write protect fault. It suggests a pinned page is getting freed into the general heap for some reason. Except there are no complaints from Xen about writes into a pagetable, so that makes it look like page is being made RO but not (left) pinned.
