LIN5-4749 : [Async BSP] CPU_HOTPLUG will cause calltrace on cgl kernel

Created: Mar 17, 2013    Updated: Dec 19, 2017
Resolved Date: Mar 19, 2013
Found In Version: 5.0.1
Fix Version: 5.0.1.1
Severity: Severe
Applicable for: Wind River Linux 5
Component/s: BSP - Async

Description

Problem Description
======================
   CPU_HOTPLUG will cause calltrace on cgl kernel, sometimes will cause
the system hang, sometimes not!

Expected Behavior
======================
the test should pass and no hang, no calltrace on the system

Observed Behavior
======================

Misc Info
======================
This test passed on sync BSP LX31 spin!
you can have look at
http://pek-rth-vm1.wrs.com/publiclog/wrl501_penguin/bts/LX31/intel-xeon-core/Canoe-Pass/cgl/CPU_HOTPLUG.log

Steps to Reproduce

1. configure a project with
/data/fast_prod/wrlinuxcgp-5011/lp05_12fa/wrlinux-5/wrlinux/configure
--enable-board=intel-xeon-core --enable-kernel=cgl
--enable-rootfs=glibc_cgl --enable-test=yes
--with-layer=wr-intel-support,/buildarea/fast_prod/wr-testing-async/bts,/buildarea/fast_prod/wr-testing-async/kts
--with-template=feature/intel-qat,feature/intel-ras --enable-jobs=16

2. build the image

make fs -j32

3. on the target:

cd /opt/wr-test; ./main_test.sh -s CPU_OTPLUG
