I just bisected a boot failure on my AMD test desktop to this patch as commit f48235900182 ("PCI/MSI: Simplify pci_irq_get_affinity()") in -next. It looks like there is a problem with the NVMe drive after this change according to the logs. Given that the hard drive is not getting mounted for journald to write logs to, I am not really sure how to get them from the machine so I have at least taken a picture of what I see on my screen; open to ideas on that front! https://github.com/nathanchance/bug-files/blob/0d25d78b5bc1d5e9c15192b3bc80676364de8287/f48235900182/crash.jpg Please let me know what information I can provide to make debugging this easier and I am more than happy to apply and test patches as needed.
