drm:drm_atomic_helper_wait_for_dependencies Errors

in flag

I am having below errors in dmesg on ubuntu 20.04 on kernel 5.4.0-81-generic. I am using ubuntu VM on vsphere 7.0.

[Fri Sep 3 20:39:13 2021] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] ERROR [CRTC:38:crtc-0] flip_done timed out [Fri Sep 3 20:39:24 2021] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] ERROR [PLANE:34:plane-0] flip_done timed out [Sun Sep 5 14:13:38 2021] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] ERROR [CRTC:38:crtc-0] flip_done timed out [Sun Sep 5 14:13:49 2021] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] ERROR [PLANE:34:plane-0] flip_done timed out

The console of VM got stuck and flooded with above errors make me unable to write things.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
