I'm definitely seeing issues with PCI interrupts with PCI passthrough, probably related to
pci-hyperv.c : commit 24196f0c7d4bba093dfa8074507f31509970319f : PCI: hv: Convert hv_pci_dev.refs from atomic_t to refcount_t pci-hyperv.c : commit 59c58ceeea9cdc6144d7b0303753e6bd26d87455 : PCI: hv: Allocate interrupt descriptors with GFP_ATOMIC I'm okay with leaving those two out but keeping the others. I suspect that since my first request was for a 4.11 base for everything we have a mismatch.
