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...
