[Touch-packages] [Bug 1511817] Re: bluetoothd consumes 100% CPU when scanning for devices, system hangs
I'm seeing bluetoothd using 100% CPU permanently on 16.04, Xenial. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1511817 Title: bluetoothd consumes 100% CPU when scanning for devices, system hangs Status in bluez package in Ubuntu: Confirmed Bug description: I'm trying to use the bluedevil wizard on Kubuntu 15.04 to add a new device (BT headset). The scan window opens but no device is found. Meanwhile, both cpu and memory usage start to increase until memory is 100% full and the system hangs! If I just kill bluedevil, then dbus-daemon keeps using 100% cpu, the only way to stop it is by manually stopping the bluetooth service. $ uname -a Linux Home1 3.19.0-32-generic #37-Ubuntu SMP Wed Oct 21 10:23:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux $ hciconfig -a hci0: Type: BR/EDR Bus: USB BD Address: 44:39:C4:19:43:C9 ACL MTU: 1022:8 SCO MTU: 183:5 DOWN RX bytes:564 acl:0 sco:0 events:29 errors:0 TX bytes:358 acl:0 sco:0 commands:29 errors:0 Features: 0xff 0xfe 0x0d 0xfe 0xd8 0x7f 0x7b 0x8f Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH HOLD SNIFF Link mode: SLAVE ACCEPT $ rfkill list 1: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: no 2: dell-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 3: phy0: Wireless LAN Soft blocked: no Hard blocked: no 4: hci0: Bluetooth Soft blocked: no Hard blocked: no $ lsmod | grep blue bluetooth 491520 23 bnep,ath3k,btusb,rfcomm $ lsusb Bus 004 Device 004: ID 0a5c:5800 Broadcom Corp.
