I'm not sure I follow. Why only unmount filesystems if it isn't possible to detect powerdown support of hardware (is that the port or the drive)? I noticed this in linux-3.10-rc2 for the first time but I think it is always enabled on previous kernels and this option only allows it to be disabled: CONFIG_USB_DEFAULT_PERSIST: Say N here if you don't want USB power session persistance enabled by default. If you say N it will make suspended USB devices that lose power get reenumerated as if they had been unplugged, causing any mounted filesystems to be lost. The persist feature can still be enabled for individual devices through the power/persist sysfs node. See Documentation/usb/persist.txt for more info. Should I file a kernel bug?
Hi again, this sounds also related for me to this...
