After the Mika's testing it turned out that they were more buggy than I had though. Oh well. The following patchset is a reworked version of the previous one. Functionality-wise the final result should be very similar, but not exactly the same. [1/6] Fix a theoretical race condition in acpi_hotplug_notify_cb(). [2/6] Move the hotplug context lock definition to the ACPI core (from ACPIPHP). [3/6] Consolidate ACPI hotplug signaling for PCI and ACPI core (this is a combination of patches [1-3/5] from the previous series). [4/6] Rework the handling of eject requests in the ACPI core. [5/6] Simplify a routine for installing hotplug notify handlers. [6/6] Dispatch ACPI hotplug notifications for "core" devices and PCI from acpi_bus_notify(). This is on top of https://lkml.org/lkml/2014/2/1/123 which in turn is on top of the current mainline. For the adventurous all this stuff is on the test-next branch of linux-pm.git.
