Hello,

I have problem with sysfs entry docked

/sys/bus/platform/devices/dock.0/docked

for my media bay DVD drive on notebook Dell Latitude E6440.

After booting linux kernel docked is set to 1 (which is correct, DVD hw is inserted into sata dock). When I undock it via sysfs entry

/sys/bus/platform/devices/dock.0/undock

then kernel remove DVD device from system (no /dev/sr0 anymore) and docked sysfs entry is set to 0.

When I press eject button on DVD drive, I hear some spin up and kernel detect DVD device again (also udev create /dev/sr0). But docked sysfs entry remains set to 0. It will never be set back to 1 - only after reboot.

So this looks like bug somewhere and probably in linux acpi dock driver... Do you know to solve this problem? More applications checking docked sysfs entry for dock presence and returning 0 will mislead them.

Here is some info from sysfs about dock:

$ grep "" /sys/bus/platform/devices/dock.0/*
/sys/bus/platform/devices/dock.0/docked:0
/sys/bus/platform/devices/dock.0/flags:32
/sys/bus/platform/devices/dock.0/modalias:acpi:LNXIOBAY:
/sys/bus/platform/devices/dock.0/type:ata_bay
/sys/bus/platform/devices/dock.0/uevent:MODALIAS=acpi:LNXIOBAY:

If you need some more info let me know. I would be happy to have working docked sysfs entry.

Does it work with 3.14(.x) by chance?
