I can't really help if you're using a custom QEMU. If you
can reproduce this with upstream QEMU then we can certainly
take a look at it. Otherwise, the problem is very likely
in whatever the custom modifications are. It should not
be too hard for whoever is responsible for those changes
to track down the problem (which is probably a new coprocessor
register definition that doesn't have the right flags on it),
so I would talk to them about this issue.
