Hi Daniel,
Note these patches:

Look at PATCH 1/2. It is about wfi instruction hex code use in CONFIG_THUMB2_KERNEL case. Even if patch tile says BE image the issue is applicable to LE thumb2 issue. Check your kernel config if THUMB2_KERNEL set the issue is applicable to you.
Hi Victor, thanks for your help.
so for the record, the issue happens when a mainline kernel is used with a Linaro u-boot which enables some hypervisor things (while the mainline u-boot doesn't). So an additional patch must be used for the kernel to get/set some more resources [1]
Thanks. Yes, I am aware about this patch. thumb2 issue will be on top of that. BTW second patch in series that I pointed you to, fixes big endian issues in [1].
Thanks, Victor
Thanks

Hi all,
I used the image:
arndale-saucy_server_20140222-611.imgI boots well but when I unplug CPU1, the kernel crashes.
It seems related to the AFTR state (an idle state of cpuidle) and the u-boot version which is 2013-rc1. It seems this issue does not happen with a more recent u-boot (I was not yet able to test it).
I don't know where to fill the bug for this release.
Chander, any pointer to the right u-boot version you are using successfully ?
Thanks
