Re: Arndale 5250 crash when unplugging CPU1

Hi Daniel,

Note these patches:

https://groups.google.com/a/linaro.org/forum/#!searchin/linaro-networking/Arndale$20hotplug/linaro-networking/MdvG8m_Bjms/YSvvIYKo4NQJ

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.

Thanks,
Victor

Arndale 5250 crash when unplugging CPU1

[Daniel Lezcano]

Hi all,

I used the image:

arndale-saucy_server_20140222-611.img

I 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
