[RPI 3B+] Bluetooth dead after recent update

[tasankovasara]

I'm surprised not to find this subject already on the board even after diligent searching, so here goes:

I've been happily using a Pi 3B+ for quite some time as an always-on box that outputs video via VNC to my phone and listens to a Bluetooth keyboard for input. Two days ago I updated the system after 8 days uptime, got a new kernel and firmware with the update and rebooted. When it came up, Bluetooth no longer worked: bluetoothd doesn't start on boot and if I manually start it, bluetoothctl reports 'no default controller available'.

Googling the issue showed that other people have had similar problems in the past couple of weeks. One Raspbian user managed to make it work again by downgrading Bluez. I tried installing the last Bluez I had in cache (I only keep one previous version of packages) but that didn't help.

Does anybody know if this is a bug or if something changed in the latest firmware / device tree / Bluez?

Thanks in advance O:)

More info: downgrading Raspberry specific packages fixed my Bluetooth.

Damn, no Linux 5 on my Pi yet. Hope this gets resolved
