Yikes. Not that I've heard of. But it's reasonably new so possibly it's not hit
distros that folks tend to run on those machines.
I'm also not clear how it would break, it could be subtle and we've not noticed.
Nathan might have more of an idea (on CC).
On my machine here everything that has an ibm,phandle also has a linux,phandle,
so we wouldn't hit that code path. But I'm not sure how representative that box
is.
cheers
