Thanks. It turns out that there are two issue here; one causing the
above boot failures and one causing the above suspend failures. I had
thought it was the same issue but now I see that suspend is still failing.

To fix the suspend issue I also needed to revert ...

 commit 3d64d18bdd1b2a6bd4af1176a596736b233606be
 Author: Rob Clark <robdclark@xxxxxxxxxxxx>
 Date:   Mon Aug 7 10:11:40 2023 -0700

     interconnect: Fix locking for runpm vs reclaim

The above commit is dependent upon the following and so I had to revert
the following too ...

 commit da051a8d3d67bb039a26bac02f439c316ac0151a
 Author: Mike Tipton <quic_mdtipton@xxxxxxxxxxx>
 Date:   Tue Mar 5 14:56:52 2024 -0800

     interconnect: Don't access req_list while it's being manipulated

So to fix all issues, I needed to revert 3 commits in total (commit
26c5e136ba4e94ad708333c9bd34039a1de397b0 plus the above 2 commits).
