[Bug 1901272] Re: Can't connect Bluetooth devices after reboot - Ubuntu 20.10 on Raspberry Pi 4

[Daniel]

First of all, this bug is so unpredictable, it's hard to replicate "on demand". It was happening when I power off device and back on and after restart it works, so it's not only what I said in description.
@Dave yes I installed your ppa and after that no device associated before were present in gnome Bluetooth setting. Pairing again first was failing but after some retries and a restart it's ok. Now I wait to see if bug is coming back but another annoying thing happened.
Two devices I use, one is Mi Silent Mouse and another is Microsoft Bluetooth Keyboard. Now after ppa the keyboard disconnect after only few seconds and it has very hard time connecting back when I press any key. With old blues it disconnect after many minutes, so it was tolerable.
After all both devices are by 4.0 LE and should not disconnect or should connect instantly with buffered keys pressed.

Bug description:
  Raspberry pi 4 4Gb ram
  Ubuntu desktop 20.10 64 bit
  After reboot no Bluetooth devices connect, scanning Bluetooth devices works, results with same device name (duplicated and with not set up status).
  Sometimes after several reboots it works.
  If I use power off and cycle power then it works fine each time.
