GPE 6D is listed in _PRW for some devices, so maybe one of them continues to trigger wakeup events? You can ask the reporter to mask that GPE via "echo mask > /sys/firmware/acpi/interrupts/gpe6D" and see if the storm goes away then. The only ACPI core issue introduced between 6.9 and 6.10 I'm aware of is the one addressed by this series https://lore.kernel.org/linux-acpi/22385894.EfDdHjke4D@xxxxxxxxxxxxx/ but this is about the EC and the problem here doesn't appear to be EC-related. It may be worth trying anyway, though.
