Steps to Reproduce

1. Build

/lpg-build/cdc/fast_prod/WRL10_22/RCPL0001_LX05/wrlinux-10/setup.sh --machines xilinx-zynqmp --distro wrlinux --distro wrlinux-graphics --dl-layers --accept-eula=yes

source environment-setup-x86_64-wrlinuxsdk-linux
source oe-init-build-env build

echo 'PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-rt"' >> conf/local.conf

bitbake wrlinux-image-std-sato


2. connect a DP Monitor to Display Port on ZCU102 target.
3. boot the target, then run 'top -n 1' when turning on the monitor.
