Bernd,
The problem is that the lca gives totally bogus intline values that
aren't 255; so the MI code thinks they are valid & never calls the
platform specific inter_route code to correct them.
Please try the appended fix, which is basically what we do on x86 SMP.
Matt Dodd said he had a better idea, but it doesn't look like he had
time to implement it. Mike Smith suggested it, and if it works for you,
I'll commit it.
Drew
