I'm not sure any more, that DISCONTIGMEM is buggy... still need more testing on this.

Just as a heads-up.

I was able to build a stable kernel (3.10-rc1 based + patches).
Dave and me still have at least two patches which made my kernel stable.
With those, I was now able to boot, install and fully upgrade to debian-unstable on my rp5470 (4xPA8700 CPUs).
In the config I used CONFIG_SMP=y (CONFIG_SMP=n crashed!), CONFIG_DISCONTIGMEM=n and CONFIG_PREEMPT=n. 
My config is attached to this mail. 
So, please stay tuned, I'm still working on getting further patches into 3.10.

And, maybe we get to a point, where we can provide new installation-medias....
