Umm.. I am not entirely sure what is going on.. but all kinds of weird
corruption seems to occur with msi-v4-part-2 that does'nt seem to be
present in v5.16-rc5. (I use NFS since ethernet in K3 platforms use
inta/intr and dma that is impacted by this series).
I will try and rebase your patches on v5.16-rc4 to be sure as well and
report back later today once i get some time.
