It produces:

acpiphp: enable_slot - physical_slot = 1
acpiphp_glue: acpiphp_enable_slot: Slot status is not ACPI_STA_ALL
acpiphp: enable_slot - physical_slot = 2
acpiphp_glue: acpiphp_enable_slot: Slot status is not ACPI_STA_ALL
acpiphp: enable_slot - physical_slot = 6
acpiphp_glue: acpiphp_enable_slot: Slot status is not ACPI_STA_ALL
acpiphp: enable_slot - physical_slot = 7
acpiphp_glue: acpiphp_enable_slot: Slot status is not ACPI_STA_ALL

I have a card in one of the slots only this time.

Yes :-)

Send privately.
