Sorry, I missed this as well - my otherwise lovely threaded email client
doesn't sort on the basis of most recent message, but thread start date.

That's really irritating. (and apologies for rendering your machine

I don't have a good idea what the cause of that would be. I don't think
I saw anything similar under qemu's mac99 model.

Is there any chance you could dump the `available` property of the
/memory node before grub is loaded? I don't think it's likely to be very
revealing but it's my best idea so far...

I've also since left IBM so I'm not likely to have a heap of time to
follow it up, unfortnately. The patch does solve a real issue on Power
systems, so I guess the next best thing if we can't root-cause it is
to make the link address compile-time configurable :/

Kind regards,
