I bisected it to the above named commit (but had to back out ba9d484ed3 (""PCI/MSI: Remove the conditional parent [un]mask logic") and then 727e914bbfbbd ("PCI/MSI: Check MSI_FLAG_PCI_MSI_MASK_PARENT in cond_[startup|shutdown]_parent()") first for a clean revert.) I have a Dell XPS-9320 laptop, and booting would hang before it switched to the xe video driver from the EFI FB driver (not sure if this is a symptom or partial cause) and I'd see a message akin to "not being able to set up DP tunnels, destroying" as the last thing printed before it hangs. (If it's important to see those messages I believe I can force a pstore crash to get them where they can be saved off, let me know). LMK if you need further info, -Kenny -- Kenneth R.
