Hello, machine with Asus P4P800-VM mainboard wakes up immediately after: echo mem >/sys/power/state or even echo disk >/sys/power/state (only when /sys/power/disk is set to "platform", which is the default) The problem disappears when unloading ehci_hcd module. There are no USB devices attached. The problem seems to be something like this: http://www.mail-archive.com/linux-usb-devel%40lists.sourceforge.net/msg54499.html /sys/devices/pci0000:00/0000:00:1d.7/power/wakeup is disabled by default /sys/devices/pci0000:00/0000:00:1d.7/usb1/power/wakeup is enabled by default, changing it to disabled fixes the problem The board has 4 USBPWxx jumpers (USBPW12, USBPW34, USBPW56 and USBPW78) that selects 5V or 5VSB as power to the corresponding USB connectors. When they're all set to 5VSB, the immediate wakeup does not appear. When any of them is set to 5V, it wakes up immediately after entering suspend. I guess that the loss of power to any of the ports (5V power is turned off in suspend) is detected as some event (overcurrent or device connect?) "ignore_oc=1" parameter to ehci_hcd modules does not change anything. -- Ondrej Zary -- 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
