If I set has_el3 to false, I can boot the 4 cores without problem. With
has_el3 set to true (default value) I am getting the above behavior (boot=
 OK
in uniprocessor mode, and misbehaving if -smp >=3D 2).

Odd. If you can point me to a test image I can use to investigate
(preferably with System.map and commit hash of kernel used to build it)
I'll see if I can find time to have a look at what's going on there.

I put my test image at the following address:

http://dl.free.fr/rADch1Xnx

You will get a tgz file with the following files in it:
  • imx6q-sabrelite.dtb
  • README
  • rootfs.cpio.gz
  • System.map=C2=A0
  • zImage
Instruction to run the image are in the README file.

The kernel is compiled using the imx_v6_v7_defconfig file (without modification) in the linux source tree

Thanks

JC
