I found out that the hangs started when I changed the config to be
somewaht compatible with E3500 instead of U5 (turning on SMP etc). I
swtched back to the original U5 custom configa and this kernel boots
again (will deal with the other config hang later when PCi is sorted
out).
So, with the latest patchset applied, I get the following oops instead:
