The host and the kexec kernel are the same, based on the current kernel version 3.10. I have tried it with kexec-tools 2.0.4.git released 30 June 2013.

i have tried to kexec a 32 bit kernel on a Freescale P2020 dual core CPU
(e500v2, revison 5.1 - pvr 8021 1051), but Kexec will hang after the "Bye!".

The host and the kexec kernel are the same, based on the current kernel version 3.10.

I have tried it with kexec-tools 2.0.4.git released 30 June 2013.

Invoking kexec with 
kexec --command-line "1 maxcpus=1 noirqdistrib reset_devices $(cat /proc/cmdline)" -t elf-ppc --dtb=rs2020.dtb \
--reuse-node="/cpus/PowerPC,P2020@0/timebase-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/bus-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/clock-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/next-level-cache" \
--reuse-node="/cpus/PowerPC,P2020@1/timebase-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/bus-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/clock-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/next-level-cache" \
--reuse-node="/cpus/PowerPC,P2020@1/cpu-release-addr" \
--reuse-node="/cpus/PowerPC,P2020@1/enable-method" \
--reuse-node="/soc@ffe00000/bus-frequency" \
--reuse-node="/soc@ffe00000/serial@4500/clock-frequency" \
--reuse-node="/soc@ffe00000/ethernet@24000/local-mac-address" \
-d -l -x vmlinux
kexec -e

This will be the result output of the run:

Kexec is still working on a Freescale 834x PowerPC CPU and the output
of kexec looks similary.

Any ideas?
