The key point is we need to figure out why the buffer is pinned in the first place. One possibility is that it is used for scanout and containing the displayed picture, but from the backtrace my guess is that the buffer is shared with a different device and pinned because of that. Can we get an lspci output for the system? Thanks in advance, Christian. --=20 You may reply to this email to add a comment.
