Booting error of L4Linux enabled SMP surpport

[Xiefeng (Stephen)]

Hi all,

I use entry L4Linux-mag-x86 in modules.list to start a L4Linux on L4Re successfully. The codes is l4re-snapshot-2014092821.
L4Linux use x86-native_deconfig complie, use l4lx-gfx.cfg to start L4Linux. This config is just set one cpu for L4Linux.

If I set l4x_cpus=2 in l4lx-gfx.cfg, use x86-mp_vPCI_defconfig and set CONFIG_NR_CPUS=2 to compile the L4Linux,
when I start L4Linux, a kernel panic happened:

Has anyone encountered this problem?
