Hi

With below steps, I always can reproduce this kernel BUG, could anyone help check it, thanks

Reproducer:
STATE=0
j=1
MAXCPUs=`nproc`

while(( ${j}<=10 ))
do
        echo ".....................................$j"
        for i in $(seq 0 `expr ${MAXCPUs} - 1`)
        do
                if ((i%4)); then
                        echo $STATE > /sys/devices/system/cpu/cpu$i/online
                fi
        done
        if [[ $STATE -eq 1 ]]; then
                STATE=0
        else
                STATE=1
        fi
        let "j++"
done

for k in $(seq 0 `expr ${MAXCPUs} - 1`)
do
        echo 1 > /sys/devices/system/cpu/cpu$k/online
done
