Hi all,
I tried the v3.14 kernel and unplugged the cpu1. That leads to a kernel
hang without any trace.
If I disable the cpuidle AFTR state through sysfs before unplugging
cpu1, it works well.
I reproduced the issue on v3.14, v3.13, v3.12, v3.11
v3.10 works fine.
Could you try to reproduce the same issue on linux-next? Some of PM
issues on Exynos should be patches there.
Tested on linux-next. Works fine.
Great, thanks.
Do you have an idea of the patch which have fixed the issue ? In order
to backport it the kernels mentioned above.
Most likely it's this one:
61557b8bac ARM: EXYNOS: Do not resume l2x0 if not enabled before suspend
Confirmed.
This patch fixes the issue.
Will you send the fix for the different kernel v3.14, v3.13, v3.12 ?
(v3.11 is EOL).
Thanks !
