Hi all, I've been trying to debug issues with my rootfs on usb 3 flash drives and suspending to ram. Symptoms: If I suspend and wake while my laptop is plugged into a charger everything works perfectly. It looks like my laptop keeps usb power on if a charger is plugged in. Without a charger the laptop locks up after waking due to ext4-fs errors. I'm not sure wether this is an issue with usb-persist power management or something else. There are other people running into similar issues: https://forum.manjaro.org/t/wake-up-problem-usb-3-0-after-suspend/10709 https://bugzilla.kernel.org/show_bug.cgi?id=30912# Things I have tried: - increasing retry count in drivers/usb/core/hub.c check_port_resume_type - http://askubuntu.com/questions/505779/suspending-with-root-on-usb Things I might try: - debug log to another device (would usb to serial work?) - inject 5v usb power using a powered hub? - anything you suggest Steffen Dirkwinkel -- 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
