keystone2 board hangs with smp kernel

keystone2 board hangs with smp kernel

[jgq516]

Hello Cyril,

I have got one TI keystone2 board, and tried different tags of tree: 
git://arago-project.org/git/projects/linux-keystone.git,
but seems the kernel always hangs as follows, and kernel runs ok if add 
"nosmp" flag.

[    0.028386] CPU: Testing write buffer coherency: ok
[    0.032493] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000
[    0.037108] hw perfevents: enabled with ARMv7 Cortex-A15 PMU driver, 
7 counters available
[    0.043763] Setting up static identity map for 0x80464628 - 0x8046465c

The uboot version which I used is from 
git://arago-project.org/git/projects/u-boot-keystone.git
with tag DEV.MCSDK-2013-01.10, I also tried other tags, but seems no 
different effect.

Could you give some advice about smp problem? Thanks in advance!

Regards,
Xiao

Oops seems Cyril has left TI since I got below infos.

Delivery to the following recipient failed permanently:

      cyril@ti.com

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain ti.com by cluster5.us.messagelabs.com. [216.82.253.147].

The error that the other server returned was:
550 Invalid recipient<cyril@ti.com>  (#5.1.1)

Could someone else can help about that? Thanks.

Xiao
