Bluetooth will not auto-start on boot, need to press an Fn key

I had an Acer S3 laptop for a while with Arch. It has an Intel wifi/bluetooth adapter, I installed awhile ago:

    02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6230 [Rainbow Peak] (rev 34)

It used to be working fine, but now it won't auto-start bluetooth on boot. A have to press Fn+(Radio Antenna) button, and then it starts. If a button is never pressed, kernel would not even see hci0.

Wifi boots and works fine, no button press necessary

Anybody knows wtf is going on? Did Intel screw up more firmware?

Can you use the user space utility rfkill to unblock it?  Does rfkill report it as a hard block, or a soft block?

I tried using rfkill, and until you press the Fn key combo, it does not see hci0, like it doesn't exist

Oh.  Ouch.

Anything in the pre-boot setup screens (sometimes erroneously called the BIOS setup) about that card?
Is it PCI-e, or USB?  Look at your journal.  Does the device enumerate only after you enable it with the Fn key?

Their Bios is a joke. Yes, it only enumerates right after I press the key.

I just thought there has to be a trick, since previously it worked without any issues
