Can you please give: > > git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git msi-v4-part-2 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.
