This was a problem I was seeing with the lkpi prior to the update from
drm-515-kmod to drm-61-kmod. I see nothing likely to be involved between the
two. I was seeing this problem while running n266789-06c083f79dd7 and
drm-515-kmod from Dec. 22 and n267556-69748e62e82a drm-61-kmod from Jan. 15.
Aside from fixing the serious limitations of running my Alder Lake graphics on
515, it also fixed the invalid TXQ and crashing issues I was seeing prior to
the update to 61.

I had previously noted that the stack backtraces from the many panics tied to
the invalid TXQ always included drm items near the top of the stack.

Have you tried drm-61-kmod? It looks like using drm-66 (I assume from git as it
is not in ports yet) has likely led to the return to the issues I had with
drm-515.

I have looked at commits to iwlwifi and the lkpi in the relevant time period
and I see nothing that looks likely in either place. I am now running a system
from Feb. 6 with no issues with either drm-61 or iwlwifi.
