[SOLVED] Bluetooth Stopped Working After Reboot

A few days ago, I installed Arch with plasma/KDE on a new laptop (EVGA SC17 laptop, latest BIOS v1.03) and got Bluetooth working with a Dualshock 4 controller. After playing some Rocket League with the connected controller, I rebooted to find that the Bluetooth adapter is no longer detected at all... Relevant pastes below.

Prior to modprobe:

$ sudo lsmod | grep blue
$ bluetoothctl
Waiting to connect to bluetoothd...

After modprobe:

$ sudo lsmod | grep blue
bluetooth             626688  11 btrtl,btintel,bnep,btbcm,btusb
ecdh_generic           24576  1 bluetooth
rfkill                 28672  9 bluetooth,cfg80211
crc16                  16384  2 bluetooth,ext4

$ rfkill list all

Things tried:
systemctl disable / enable bluetooth
rfkill unblock all
rfkill unblock bluetooth
rfkill unblock all as a system service ran at boot
rmmod / modprobe btusb
Uninstalled all bluez packages, reinstalled
Installed bluez-util-compat as well, tested hcitool dev (no devices listed) and hciconfig -a ... commands from Wiki
Added below to /etc/bluetooth/main.conf

[Policy]
AutoEnable=true

Rebooted dozens of times and tested different configurations of all things above.
Checked for hardware switches to turn on/off radios - only one function key exists (airplane mode), does not toggle Bluetooth.
Checked BIOS for settings that control radios - nothing there.

Could someone provide some direction on what to try next? I've run out of ideas.

Re: [SOLVED] Bluetooth Stopped Working After Reboot

No ideas?

I'd rather not have to wipe and reinstall just to fix a Bluetooth issue.

Re: [SOLVED] Bluetooth Stopped Working After Reboot

Solved with a CMOS reset for some reason.
