Now I am able to successfully install all imx modules after the resume (no hang). But, I got some errors after install finish: [drm] disabling vblank on crtc 1 [IMX]: imx_drm_disable_vblank - called [drm:drm_atomic_helper_commit_cleanup_done] *ERROR* [CRTC:24:crtc-0] flip_done timed out Also I am able to start the weston successfully. But I see LCD/HDMI display is not working (only some backlight is visible). And, I noticed, weston also reports the following errors: imx-ipuv3 2400000.ipu: DC stop timeout after 50 ms [IMX]: drm_crtc_vblank_off - called [IMX]: imx_drm_disable_vblank - called INFO: rcu_preempt detected stalls on CPUs/tasks: { 1} (detected by 0, t=6002 jiffies, g=289, c=288, q=8) Task dump for CPU 1: weston R running 0 306 1 0x00000000 [] (__schedule) from [<00080193>] (0x80193) Do you have any clue about these errors ?
