Hi Seif,
Another possible reason is CONFIG_HOTPLUG_CPU is enabled and I checked
defconfig its also enabled.
config HOTPLUG_CPU
bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"
depends on SMP && HOTPLUG && EXPERIMENTAL
help
Say Y here to experiment with turning CPUs off and on. CPUs
can be controlled through /sys/devices/system/cpu.
So it looks to turn off cpu hotplug is also a solution if we do not
support for cpu hotplug with Armada XP.
Could you confirm this?
Thanks a lot.
