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. Thank you for your understanding. ** Tags added: needs-kernel-logs needs-upstream-testing ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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: Incomplete Bug description: I am experiencing unstable bluetooth connections between a USB bluetooth dongle and headset. I get a ton of lines like Dec 1 04:09:51 localhost kernel: [ 264.372205] hci_scodata_packet: hci0 SCO packet for unknown connection handle 65261 in syslog. The bluetooth connection also usually breaks down about 10 seconds into a Skype call. I cannot know if the two phenomena are actually related. Dec 1 04:09:52 localhost kernel: [ 264.392198] hci_scodata_packet: hci0 SCO packet for unknown connection handle 65072 Dec 1 04:09:52 localhost kernel: [ 264.402199] hci_scodata_packet: hci0 SCO packet for unknown connection handle 65493 Dec 1 04:10:26 localhost bluetoothd[1756]: Audio connection got disconnected Dec 1 04:10:26 localhost pulseaudio[1936]: ratelimit.c: 4802 events suppressed Dec 1 04:10:35 localhost pulseaudio[1936]: ratelimit.c: 428 events suppressed I believe this is a Ubuntu-induced regression, I was unable to reproduce the problem with a mainline kernel today. confirmed affected: vmlinuz-2.6.32-35-generic (latest lucid kernel) confirmed affected: vmlinuz-3.0.0-13-generic apparently unaffected: vmlinuz-3.2.0-999-generic from today (or rather Nov 30th) FWIW, the mainline kernel seems to have a stable bluetooth connection but syslog gets flooded there as well.
