Given that all of the reports are in cases when the adjustment is *not* being done (and only a message is being printed), I can only assume that the breakage results from the adding of PCI_BASE_ADDRESS_SPACE_IO into the resource flags. I considered this unconditional setting of the flags odd already in the original code, and added this extra flag only for consistency reasons (because the settings reported by X indicated that this was missing). Perhaps the adjustment (original and the added extra flag) shouldn't be done if IORESOURCE_IO wasn't already set. Perhaps one of those seeing the issue could try out returning from the function right after that printk(), without any adjustment to the flags.
