Could you help to give any suggestions on this? Thanks very much.

Greg, Stable team,

Please backport upstream commit

010e3e68cd9c ("drm/i915: Remove vma from object on destroy, not close")

to v4.14. It fixes a previously backported commit:

Fixes: 6209cb514d97 ("drm/i915: Flush pending GTT writes before unbinding")

Now queued up, thanks.
