Hi, I was able to fix the problem in the local reproducer. The problem was fixed by changing the following kernel config: -# CONFIG_DRM_FBDEV_EMULATION is not set +CONFIG_DRM_FBDEV_EMULATION=y This option was not present in the older kernels because it show up in the commit: commit e8154c8f3022b417c7bdb52f31fdb1a0fc525cf6 Author: Rob Clark <rclark> Date: Tue May 17 15:59:52 2016 -0400 [drm] upstream sync to v4.5 Which appeared in the: git describe e8154c8f3022b417c7bdb52f31fdb1a0fc525cf6 kernel-3.10.0-379.el7-5158-ge8154c8 That was after the 7.2 release. I build a test kernel based on the latest z-stream kernel, they are here: http://file.rdu.redhat.com/~daolivei/BZ1452769/ Vishal, could you please deliver this test kernel to the customer to confirm that it fixes the problem? -- Daniel
