Hi,
I tried building kexec with gcc-4.3 from the cell sdk-3.1
and the resulting binary didn't work correctly. It works
OK with the gcc-4.1 from the same (sdk-3.1).
Here is the last thing seen, then the system hangs:
Starting new kernel
kexec: waiting for cpu 1 (physical 1) to go down
Invalid tag 26 scanning flattened device tree !
Invalid tag 26 scanning flattened device tree !
Invalid tag 26 scanning flattened device tree !
Does anyone have any ideas?
-Geoff

You mean building kexec-tools? Or building the kernel?
cheers

The kexec program in kexec-tools.

Right. In that case I'd guess there's a bug in the kexec-tools DT
creation code, that's being exposed by the new gcc.
If you compare the DT from a working and non-working version it
shouldn't be too hard to track down.

I finally got around to investigating this, and now
I can't reproduce it. I tried with 2.6.29 and the
current mainline kernel. I can only guess it was
something about the kernel at the time.
