Looks like something doesn't release that lock. I added printks what you
suggested and after first hotplug/unplug last messages I get are:

[   64.914639] ACPI: \_SB_.PCI0.RP05: ACPI_NOTIFY_BUS_CHECK event
[   64.914640] ACPI: \_SB_.PCI0.RP05: BEFORE mutex_lock()

Then running sysrq-w I get following task as blocked:
