There are two battery changes in linux-next now that are not present
in the mainline

2a2aad34362b ACPI: battery: remove redundant old_present check on insertion
706ac4aa536f ACPI: battery: use cache_time as cache "enabled"

Does reverting any of them help? Or is the problem present in the mainline too?
