Linux Guest [vmwgfx] *ERROR* SVGA device lockup

[brian-vbox]

Hi,

I'm running a Linux guest on a Windows host and every so often the display will lock up. It's happened maybe 3 times in the last month and I haven't been able to correlate it with anything specific.

By lock up, I mean that it appears that the display stops updating. Input (at least mouse events) appear to work, but when it starts to lock-up, the display does not update in response to any input events until a few seconds go by. Pretty quickly, this behavior degrades to the point where it appears completely frozen and no more updates occur.

I can ssh in from my host and interact, so it seems it is just a display driver issue. dmesg shows the following:

[70545.554435] [drm:vmw_fallback_wait [vmwgfx]] *ERROR* SVGA device lockup. [70548.553727] [drm:vmw_fallback_wait [vmwgfx]] *ERROR* SVGA device lockup. [70558.765785] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [CRTC:38:crtc-0] flip_done timed out [73420.314255] [drm:vmw_fallback_wait [vmwgfx]] *ERROR* SVGA device lockup. [73423.314445] [drm:vmw_fallback_wait [vmwgfx]] *ERROR* SVGA device lockup. [73433.384206] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [CRTC:38:crtc-0] flip_done timed out

Not sure what else to check, but can do whatever is needed to debug next time it happens. Just let me know.

I also see these messages appearing occasionally before hand, but they look to occur fairly regularly in the log without any other symptoms, so I don't know if they are related or not.

[54955.536381] [drm:vmw_msg_ioctl [vmwgfx]] *ERROR* Failed to open channel.

I can provide more detailed hardware info (it's a Dell XPS 9500 using an i7-10857H w/ 32GB), os specifics (Win10, Ubuntu 20.04), and system config (I run 2 external displays on which I use my linux guest) or whatever else is needed.

I will attach my VBOX.log

Thanks for any help, Brian

Tried with 3D enabled in the VM settings? That would give a very valuable data point.
