2013-07-31 13:11:42 Chas. Owens description I have a Logitech K760 Bluetooth keyboard. This keyboard has three buttons that allow you to connect to three different machines via Bluetooth. I have button three mapped to my Ubuntu box. When I hit button one and then quickly hit button three, the kernel crashes. If I wait a long period of time, it does not crash. The logs (see end for full trace) seem to indicate that there is a problem with the kernel trying to create file that already exists: sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21' I assume this is happening because the kernel has yet to clean up after the disconnection before the device tries to reconnect. My current workaround is to wait a while before hitting button 3 when I accidentally hit button 1. It would be nice if I reduce the timeout before the kernel cleans up the after the device to shorten the period of time I have to wait. Here I have hit button 1 and waited a few seconds: Jul 31 07:25:01 LD-cowens kernel: [ 199.114124] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Jul 31 07:25:06 LD-cowens kernel: [ 204.105779] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Then I hit button 3: Jul 31 07:25:31 LD-cowens kernel: [ 229.279867] hid-generic 0005:046D:B316.0006: unknown main item tag 0x0 Jul 31 07:25:31 LD-cowens kernel: [ 229.293875] input: Logitech K760 as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21/input16 Jul 31 07:25:31 LD-cowens kernel: [ 229.294115] hid-generic 0005:046D:B316.0006: input,hidraw4: BLUETOOTH HID v1.1b Keyboard [Logitech K760] on 00:02:72:dd:e9:e1 Hit button 1 and wait a few seconds: Jul 31 07:25:47 LD-cowens kernel: [ 244.558409] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Jul 31 07:25:52 LD-cowens kernel: [ 249.550056] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Hit button 3: Jul 31 07:26:15 LD-cowens kernel: [ 272.731818] hid-generic 0005:046D:B316.0007: unknown main item tag 0x0 Jul 31 07:26:15 LD-cowens kernel: [ 272.770990] input: Logitech K760 as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21/input17 Jul 31 07:26:15 LD-cowens kernel: [ 272.771187] hid-generic 0005:046D:B316.0007: input,hidraw4: BLUETOOTH HID v1.1b Keyboard [Logitech K760] on 00:02:72:dd:e9:e1 Hit button 1 and then button 3 without waiting long: Jul 31 07:26:39 LD-cowens kernel: [ 296.631605] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Jul 31 07:26:40 LD-cowens kernel: [ 298.165703] ------------[ cut here ]------------ Jul 31 07:26:40 LD-cowens kernel: [ 298.165714] WARNING: at /build/buildd/linux-3.8.0/fs/sysfs/dir.c:536 sysfs_add_one+0xb6/0xf0() Jul 31 07:26:40 LD-cowens kernel: [ 298.165717] Hardware name: HP Elite 7100 Microtower PC Jul 31 07:26:40 LD-cowens kernel: [ 298.165720] sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21' Jul 31 07:26:40 LD-cowens kernel: [ 298.165722] Modules linked in: hidp btusb ath3k parport_pc(F) ppdev(F) rfcomm bnep bluetooth snd_hda_codec_hdmi snd_hda_codec_realtek coretemp radeon kvm_intel kvm snd_hda_intel snd_hda_codec snd_hwdep(F) snd_pcm(F) snd_page_alloc(F) snd_seq_midi(F) snd_seq_midi_event(F) snd_rawmidi(F) ttm wmi drm_kms_helper snd_seq(F) snd_seq_device(F) drm snd_timer(F) gpio_ich snd(F) joydev(F) mac_hid mei lpc_ich i2c_algo_bit soundcore(F) lp(F) parport(F) psmouse(F) serio_raw(F) microcode(F) hid_generic usbhid hid firewire_ohci firewire_core r8169 ahci(F) libahci(F) crc_itu_t(F) Jul 31 07:26:40 LD-cowens kernel: [ 298.165784] Pid: 7, comm: kworker/u:0H Tainted: GF 3.8.0-27-generic #40-Ubuntu Jul 31 07:26:40 LD-cowens kernel: [ 298.165786] Call Trace: Jul 31 07:26:40 LD-cowens kernel: [ 298.165796] [<c104a502>] warn_slowpath_common+0x72/0xa0 Jul 31 07:26:40 LD-cowens kernel: [ 298.165802] [<c11c1076>] ?

This keyboard has three buttons that allow you to connect to three different machines via Bluetooth. I have button three mapped to my Ubuntu box. When I hit button one and then quickly hit button three, the kernel crashes. If I wait a long period of time, it does not crash. The logs (see end for full trace) seem to indicate that there is a problem with the kernel trying to create file that already exists: sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21' I assume this is happening because the kernel has yet to clean up after the disconnection before the device tries to reconnect. My current workaround is to wait a while before hitting button 3 when I accidentally hit button 1. It would be nice if I reduce the timeout before the kernel cleans up the after the device to shorten the period of time I have to wait. Here I have hit button 1 and waited a few seconds: Jul 31 07:25:01 LD-cowens kernel: [ 199.114124] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Jul 31 07:25:06 LD-cowens kernel: [ 204.105779] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Then I hit button 3: Jul 31 07:25:31 LD-cowens kernel: [ 229.279867] hid-generic 0005:046D:B316.0006: unknown main item tag 0x0 Jul 31 07:25:31 LD-cowens kernel: [ 229.293875] input: Logitech K760 as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21/input16 Jul 31 07:25:31 LD-cowens kernel: [ 229.294115] hid-generic 0005:046D:B316.0006: input,hidraw4: BLUETOOTH HID v1.1b Keyboard [Logitech K760] on 00:02:72:dd:e9:e1 Hit button 1 and wait a few seconds: Jul 31 07:25:47 LD-cowens kernel: [ 244.558409] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Jul 31 07:25:52 LD-cowens kernel: [ 249.550056] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Hit button 3: Jul 31 07:26:15 LD-cowens kernel: [ 272.731818] hid-generic 0005:046D:B316.0007: unknown main item tag 0x0 Jul 31 07:26:15 LD-cowens kernel: [ 272.770990] input: Logitech K760 as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21/input17 Jul 31 07:26:15 LD-cowens kernel: [ 272.771187] hid-generic 0005:046D:B316.0007: input,hidraw4: BLUETOOTH HID v1.1b Keyboard [Logitech K760] on 00:02:72:dd:e9:e1 Hit button 1 and then button 3 without waiting long: Jul 31 07:26:39 LD-cowens kernel: [ 296.631605] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Jul 31 07:26:40 LD-cowens kernel: [ 298.165703] ------------[ cut here ]------------ Jul 31 07:26:40 LD-cowens kernel: [ 298.165714] WARNING: at /build/buildd/linux-3.8.0/fs/sysfs/dir.c:536 sysfs_add_one+0xb6/0xf0() Jul 31 07:26:40 LD-cowens kernel: [ 298.165717] Hardware name: HP Elite 7100 Microtower PC Jul 31 07:26:40 LD-cowens kernel: [ 298.165720] sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21' Jul 31 07:26:40 LD-cowens kernel: [ 298.165722] Modules linked in: hidp btusb ath3k parport_pc(F) ppdev(F) rfcomm bnep bluetooth snd_hda_codec_hdmi snd_hda_codec_realtek coretemp radeon kvm_intel kvm snd_hda_intel snd_hda_codec snd_hwdep(F) snd_pcm(F) snd_page_alloc(F) snd_seq_midi(F) snd_seq_midi_event(F) snd_rawmidi(F) ttm wmi drm_kms_helper snd_seq(F) snd_seq_device(F) drm snd_timer(F) gpio_ich snd(F) joydev(F) mac_hid mei lpc_ich i2c_algo_bit soundcore(F) lp(F) parport(F) psmouse(F) serio_raw(F) microcode(F) hid_generic usbhid hid firewire_ohci firewire_core r8169 ahci(F) libahci(F) crc_itu_t(F) Jul 31 07:26:40 LD-cowens kernel: [ 298.165784] Pid: 7, comm: kworker/u:0H Tainted: GF 3.8.0-27-generic #40-Ubuntu Jul 31 07:26:40 LD-cowens kernel: [ 298.165786] Call Trace: Jul 31 07:26:40 LD-cowens kernel: [ 298.165796] [<c104a502>] warn_slowpath_common+0x72/0xa0 Jul 31 07:26:40 LD-cowens kernel: [ 298.165802] [<c11c1076>] ?

2013-08-03 16:47:21 penalvch description I have a Logitech K760 Bluetooth keyboard. This keyboard has three buttons that allow you to connect to three different machines via Bluetooth. I have button three mapped to my Ubuntu box. When I hit button one and then quickly hit button three, the kernel crashes. If I wait a long period of time, it does not crash. The logs (see end for full trace) seem to indicate that there is a problem with the kernel trying to create file that already exists: sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21' I assume this is happening because the kernel has yet to clean up after the disconnection before the device tries to reconnect. My current workaround is to wait a while before hitting button 3 when I accidentally hit button 1. It would be nice if I reduce the timeout before the kernel cleans up the after the device to shorten the period of time I have to wait. Here I have hit button 1 and waited a few seconds: Jul 31 07:25:01 LD-cowens kernel: [ 199.114124] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Jul 31 07:25:06 LD-cowens kernel: [ 204.105779] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Then I hit button 3: Jul 31 07:25:31 LD-cowens kernel: [ 229.279867] hid-generic 0005:046D:B316.0006: unknown main item tag 0x0 Jul 31 07:25:31 LD-cowens kernel: [ 229.293875] input: Logitech K760 as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21/input16 Jul 31 07:25:31 LD-cowens kernel: [ 229.294115] hid-generic 0005:046D:B316.0006: input,hidraw4: BLUETOOTH HID v1.1b Keyboard [Logitech K760] on 00:02:72:dd:e9:e1 Hit button 1 and wait a few seconds: Jul 31 07:25:47 LD-cowens kernel: [ 244.558409] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Jul 31 07:25:52 LD-cowens kernel: [ 249.550056] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Hit button 3: Jul 31 07:26:15 LD-cowens kernel: [ 272.731818] hid-generic 0005:046D:B316.0007: unknown main item tag 0x0 Jul 31 07:26:15 LD-cowens kernel: [ 272.770990] input: Logitech K760 as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21/input17 Jul 31 07:26:15 LD-cowens kernel: [ 272.771187] hid-generic 0005:046D:B316.0007: input,hidraw4: BLUETOOTH HID v1.1b Keyboard [Logitech K760] on 00:02:72:dd:e9:e1 Hit button 1 and then button 3 without waiting long: Jul 31 07:26:39 LD-cowens kernel: [ 296.631605] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5 Jul 31 07:26:40 LD-cowens kernel: [ 298.165703] ------------[ cut here ]------------ Jul 31 07:26:40 LD-cowens kernel: [ 298.165714] WARNING: at /build/buildd/linux-3.8.0/fs/sysfs/dir.c:536 sysfs_add_one+0xb6/0xf0() Jul 31 07:26:40 LD-cowens kernel: [ 298.165717] Hardware name: HP Elite 7100 Microtower PC Jul 31 07:26:40 LD-cowens kernel: [ 298.165720] sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21' Jul 31 07:26:40 LD-cowens kernel: [ 298.165722] Modules linked in: hidp btusb ath3k parport_pc(F) ppdev(F) rfcomm bnep bluetooth snd_hda_codec_hdmi snd_hda_codec_realtek coretemp radeon kvm_intel kvm snd_hda_intel snd_hda_codec snd_hwdep(F) snd_pcm(F) snd_page_alloc(F) snd_seq_midi(F) snd_seq_midi_event(F) snd_rawmidi(F) ttm wmi drm_kms_helper snd_seq(F) snd_seq_device(F) drm snd_timer(F) gpio_ich snd(F) joydev(F) mac_hid mei lpc_ich i2c_algo_bit soundcore(F) lp(F) parport(F) psmouse(F) serio_raw(F) microcode(F) hid_generic usbhid hid firewire_ohci firewire_core r8169 ahci(F) libahci(F) crc_itu_t(F) Jul 31 07:26:40 LD-cowens kernel: [ 298.165784] Pid: 7, comm: kworker/u:0H Tainted: GF 3.8.0-27-generic #40-Ubuntu Jul 31 07:26:40 LD-cowens kernel: [ 298.165786] Call Trace: Jul 31 07:26:40 LD-cowens kernel: [ 298.165796] [<c104a502>] warn_slowpath_common+0x72/0xa0 Jul 31 07:26:40 LD-cowens kernel: [ 298.165802] [<c11c1076>] ?

This keyboard has three buttons that allow you to connect to three different machines via Bluetooth. I have button three mapped to my Ubuntu box. When I hit button one and then quickly hit button three, the kernel crashes. If I wait a long period of time, it does not crash. The logs (see end for full trace) seem to indicate that there is a problem with the kernel trying to create file that already exists:     sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21' I assume this is happening because the kernel has yet to clean up after the disconnection before the device tries to reconnect. My current workaround is to wait a while before hitting button 3 when I accidentally hit button 1. It would be nice if I reduce the timeout before the kernel cleans up the after the device to shorten the period of time I have to wait.
