I can still crash my x86_64 box with Christoph's program.
So it looks like the problem is arch specific. Test program runs fine on
ia64.

For what it is worth:
Christoph's test program runs fine on my 32 GB, 4 socket, 8 core Opteron 64
Opteron 64? A new exciting upcomming product? @)
box with 2.6.16-rc1.
Yes it also works on my test box and also some other simple tests with MPOL_BIND.
But we had similar reports on two different systems, so there's very likely a problem.
Just need to reproduce it somehow.
