[Kernel-packages] [Bug 898347] Re: syslog flooded with hci_scodata_packet: hci0 SCO packet for unknown connection handle
I believe i'm suffering from the same issue. The headset is Nokia BH-216 with Dell Latitude E6510 and Ubuntu 14.04. Connection can work for 20 minutes, or disconnect in one. After reconnecting it again works for a while. Dmesg is flooded with lines like this: [ 3424.806640] Bluetooth: hci0 SCO packet for unknown connection handle 6 [ 3424.806644] Bluetooth: hci0 SCO packet for unknown connection handle 6 [ 3499.700652] Bluetooth: hci0 SCO packet for unknown connection handle 6 [ 3499.700658] Bluetooth: hci0 SCO packet for unknown connection handle 6 [ 3499.700661] Bluetooth: hci0 SCO packet for unknown connection handle 6 Linux villendell 3.13.0-39-generic #66-Ubuntu SMP Tue Oct 28 13:30:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/898347 Title: syslog flooded with hci_scodata_packet: hci0 SCO packet for unknown connection handle Status in “linux” package in Ubuntu: Confirmed Bug description: I am experiencing unstable bluetooth connections between a USB bluetooth dongle and headset.

[Kernel-packages] [Bug 898347] Re: syslog flooded with hci_scodata_packet: hci0 SCO packet for unknown connection handle
Rolf Leggewie, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications-Accessories-Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux replace-with-bug-number Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.
