Software: Ubuntu 12.10 amd64, Linux 3.5.0-25.39-generic
Hardware: Thinkpad X230, Ultrabase series 3, generic Samsung SATA hard drive in Ultrabase HDD bay
To reproduce:
Boot system, use drive in dock bay. Suspend while docked, undock, "go to work", resume (dock bay drive previously on /dev/sdb1 isn't there anymore), suspend again, "return home", dock, resume.
Now the bay drive isn't shown anymore, there is no /dev/sdb or any hint of its existence in udisks, fdisk, mtab, ...
Running 'udevadm info -ap /sys/devices/platform/dock.2' simply shows 'ATTR{docked}=="0"' among others.
Workaround:
Simply undocking and redocking while the system is awake repopulates /dev/sdb1. As I haven't figured out a software way to do it, this amounts to pulling the docks lever and dropping it again every time after docking.
More:
Undocking before suspend (before "going to work") is clunky (have to open lid once more) but fixes this problem.
As does resuming before docking again (after "return home"), but I'd like to avoid having to open the lid at all, and this is equivalent to the workaround described above.
I don't know why allowing it to register the undock before suspending the first time makes a difference when resuming in a docked-again state.
