Hi Vinicius, not sure if the bt is about the same issue. I was able to trigger this after a pairing failed (the reason for this is still unknown to me, I am debugging this. See the urb failures) and then stopping bluetoothd. BTW, this is bluetooth-next from yesterday. cheers, daniel Jan 3 10:08:24 candlejack kernel: [66006.248288] usb 5-2: BOGUS urb flags, 2 --> 0 Jan 3 10:08:24 candlejack kernel: [66006.248293] Bluetooth: hci0 urb ffff8801fcfe83c0 submission failed (22) Jan 3 10:08:28 candlejack kernel: [66010.256231] usb 5-2: BOGUS urb flags, 2 --> 0 Jan 3 10:08:28 candlejack kernel: [66010.256237] Bluetooth: hci0 urb ffff8800375693c0 submission failed (22) Jan 3 10:09:00 candlejack abrt: detected unhandled Python exception in './test-device' Jan 3 10:09:02 candlejack abrt: detected unhandled Python exception in './test-device' Jan 3 10:09:04 candlejack bluetoothd[4913]: Terminating Jan 3 10:09:05 candlejack kernel: [66046.284261] Bluetooth: unknown link type 97 Jan 3 10:09:05 candlejack kernel: [66046.284281] BUG: unable to handle kernel paging request at 0000000000050002 Jan 3 10:09:05 candlejack kernel: [66046.284330] IP: [<ffffffff817ea271>] _raw_spin_lock_irqsave+0x11/0x30 Jan 3 10:09:05 candlejack kernel: [66046.284368] PGD 0 Jan 3 10:09:05 candlejack kernel: [66046.284386] Oops: 0002 [#1] SMP Jan 3 10:09:05 candlejack kernel: [66046.284414] CPU 1 Jan 3 10:09:05 candlejack kernel: [66046.284427] Modules linked in: rfcomm bnep btusb bluetooth [last unloaded: scsi_wait_scan] Jan 3 10:09:05 candlejack kernel: [66046.284498] Jan 3 10:09:05 candlejack kernel: [66046.284510] Pid: 4913, comm: bluetoothd Tainted: G I 3.2.0-rc2+ #5 Hewlett-Packard HP xw4600 Workstation/0AA0h Jan 3 10:09:05 candlejack kernel: [66046.284567] RIP: 0010:[<ffffffff817ea271>] [<ffffffff817ea271>] _raw_spin_lock_irqsave+0x11/0x30 Jan 3 10:09:05 candlejack kernel: [66046.284607] RSP: 0018:ffff8801a6141c98 EFLAGS: 00010096 Jan 3 10:09:05 candlejack kernel: [66046.284629] RAX: 0000000000000296 RBX: 0000000000050002 RCX: 0000000000000047 Jan 3 10:09:05 candlejack kernel: [66046.284656] RDX: 0000000000000100 RSI: ffff8801a6141ce0 RDI: 0000000000050002 Jan 3 10:09:05 candlejack kernel: [66046.284689] RBP: ffff8801a6141c98 R08: 0000000000000000 R09: 0000000000000000 Jan 3 10:09:05 candlejack kernel: [66046.284716] R10: 0000000000000000 R11: 0000000000000001 R12: ffff880165a9b4f0 Jan 3 10:09:05 candlejack kernel: [66046.284745] R13: ffff8801a6141ce0 R14: 0000000000050003 R15: 000000000000000f Jan 3 10:09:05 candlejack kernel: [66046.284772] FS: 00007f8ff6ff1740(0000) GS:ffff88023fc80000(0000) knlGS:0000000000000000 Jan 3 10:09:05 candlejack kernel: [66046.284802] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Jan 3 10:09:05 candlejack kernel: [66046.284825] CR2: 0000000000050002 CR3: 0000000194066000 CR4: 00000000000406e0 Jan 3 10:09:05 candlejack kernel: [66046.284852] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 Jan 3 10:09:05 candlejack kernel: [66046.284880] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Jan 3 10:09:05 candlejack kernel: [66046.284907] Process bluetoothd (pid: 4913, threadinfo ffff8801a6140000, task ffff880199d6cb00) Jan 3 10:09:05 candlejack kernel: [66046.284938] Stack: Jan 3 10:09:05 candlejack kernel: [66046.284951] ffff8801a6141cc8 ffffffff81052c89 ffff880165a9b4f0 0000000000000000 Jan 3 10:09:05 candlejack kernel: [66046.285006] ffff8802361e15d0 ffff8800512a6330 ffff8801a6141d18 ffffffff81053f4e Jan 3 10:09:05 candlejack kernel: [66046.285062] ffffffffa002a7c2 ffff8801a6141cc0 0000000000000000 ffff880165a9b400 Jan 3 10:09:05 candlejack kernel: [66046.285113] Call Trace: Jan 3 10:09:05 candlejack kernel: [66046.285131] [<ffffffff81052c89>] lock_timer_base+0x39/0x70 Jan 3 10:09:05 candlejack kernel: [66046.285157] [<ffffffff81053f4e>] del_timer+0x3e/0x110 Jan 3 10:09:05 candlejack kernel: [66046.285187] [<ffffffffa00080d4>] hci_conn_del+0x44/0x290 [bluetooth] Jan 3 10:09:05 candlejack kernel: [66046.285217] [<ffffffffa00083a0>] hci_conn_hash_flush+0x80/0xf0 [bluetooth] Jan 3 10:09:05 candlejack kernel: [66046.285249] [<ffffffffa0002c1b>] hci_dev_do_close+0xbb/0x320 [bluetooth] Jan 3 10:09:05 candlejack kernel: [66046.285249] [<ffffffffa00047dd>] hci_dev_close+0x2d/0x70 [bluetooth] Jan 3 10:09:05 candlejack kernel: [66046.285249] [<ffffffffa001552a>] hci_sock_ioctl+0x1aa/0x3f0 [bluetooth] Jan 3 10:09:05 candlejack kernel: [66046.285249] [<ffffffff817f1a96>] ?
