Hi Luis, adding Daniel as well.
first of all can you please create a bug report for this here: https://gitlab.freedesktop.org/drm/amd/-/issues This way we can better track issues.
Then what seems to happen is that somebody is using the TTM pages in a way they are not supposed to be used.
We have found a bunch of bugs in for example KVM since adding that commit and I have the strong suspicion that is just another one of those.
