Hmmm... very odd. I unfortunately don't have a machine that can easily do S4 at hand, but I did test this on an IVB with XHCI_RESET_ON_RESUME in S3 (essentially the same code path), and I didn't run into any problems. How exactly does your machine fail on resume? Is it a kernel crash or just a hang? Can you try getting some debug output (by setting 'echo N > /sys/module/printk/parameters/console_suspend' and trying to catch the crash on the screen or a serial line, or maybe through pstore)? I really don't see much that could go wrong with this patch, so without more info it will be hard to understand your problem. Also, I noticed that you have two HID devices plugged in during suspend. Does it make a difference if you have different devices (e.g. a mass storage stick) or none at all? -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
