[Bug 2129192] Re: [mt7925e] bluetooth stopped working after latest update

 

When I initially rebooted the system after the upgrade, my Logitech Bolt
receiver wasn't working and Bluetooth was not working. I also have an
older Logitech Unifying reciever and that one did work. The Logitech
Bolt receiver is the one that you see failed. I then moved the Bolt
reciever to a different USB port and it did start working again. At that
time, however, Bluetooth remained unavailable despite multiple reboots,
a cold restart, and double checking the bios to ensure it was enabled.

Today, however, I rebooted the system with only a wired keyboard and
mouse attached and the bluetooth worked. I then put back each Logitech
reciever one at a time and both worked and the bluetooth remained
working. So now it's all working and I'm puzzled.

You can close this bug report, but maybe there is a bug somewhere
involving a race condition, or similar, initializing the Logitech
receivers and that's somehow affecting the Bluetooth device
initialization? Or there's an instability related to the Logitech
recievers and the Bluetooth together? I don't know.

Thanks for your attention to the problem.

  [mt7925e] bluetooth stopped working after latest update

Bug description:
  I updated this morning. Bluetooth immediately stopped working. I check
  my computers bios settings and it is enabled. It appears to have been
  caused by the update. It has disappeared as option in my deskotp
  settings, I simply see "No blueooth found" in the settings panel.  I
  can't identify the exact package that I updated. I accepted all the
  updates, rebooted, and at that point there was no more bluetooth.
