Bluetooth device sometimes instantly turns off again after turning it on

[ellie]

Sometimes when turning on bluetooth in the gnome bluetooth panel, it is shown as "On" for like a second and reverts back to "Off". This is what I see in dmesg:

[1199362.625284] usb 1-1.4: Product: Broadcom Bluetooth Device
[1199362.625286] usb 1-1.4: Manufacturer: Broadcom Corp

[1199362.839031] usb 1-1.4: USB disconnect, device number 10

[1199371.330556] usb 1-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[1199371.330559] usb 1-1.4: Product: Broadcom Bluetooth Device
[1199371.330560] usb 1-1.4: Manufacturer: Broadcom Corp
[1199371.330562] usb 1-1.4: SerialNumber: EC55F9EFBB65
[1199371.544424] usb 1-1.4: USB disconnect, device number 11

This situation is usually triggered after waking up from suspend, and then permanent up to the next reboot.
I would assume the USB disconnect is the problem. I don't have bluetooth disabled in the BIOS settings.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.19 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

It doesn't happen *every* time when waking up from suspend, just sometimes. I can try switching to the mainline kernel and run it for a while, and hope it happens again.

However, I had exactly the same problem on Fedora 21 through multiple kernel upgrades.

(I don't have the bluetooth headphones long enough to know if this ever not happened)

Jonas Thiem, as per http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x220 an update to your computer's buggy and outdated BIOS is available (1.40). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed.

Thank you for your understanding.
