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. 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.
