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.
