Hi David,
Thank for your patch,
I would like to reproduce the calltrace before moving forward, but have trouble to reproduce the original issue.
I'm working with vfio-pci and CX-4/5 cards on daily basis, tried manually enter into D3 state now, and it worked for me.
Can you please post your full calltrace, and "lspci -s PCI_ID -vv" output?
