I verified that by running `lspci -vvv | grep DevSta: | > grep +` before/after every resume, and NonFatalError on all c4:00 devices > flips only after the event. Interesting, was PCI DevSta: NonFatalErr+ ever set with the 'Forced MSI onl= y' patch after resume? i.e. Does MSI-X usage on xHC trigger the DevSta: NonFatalErr+, causing xHC interrupt handler to hot be called or, is there something else causing PCI DevSta: NonFatalErr+ in resume which for some reason only affects/omits MSI-X handler while MSI work and handler is called as it should. --=20 You may reply to this email to add a comment.
