Hi Leann. Thanks for you reply.
I get this message with 2.6.24.16.18 after a couple of minutes: [ 1108.597128] irq 19: nobody cared (try booting with the "irqpoll" option) [ 1108.597143] Pid: 0, comm: swapper Not tainted 2.6.24-16-generic #1 [ 1108.597147] [ 1108.597148] Call Trace: [ 1108.597152] <IRQ> [<ffffffff8027ad8e>] __report_bad_irq+0x1e/0x80 [ 1108.597203] [<ffffffff8027b09d>] note_interrupt+0x2ad/0x2e0 [ 1108.597230] [<ffffffff8027bbe1>] handle_fasteoi_irq+0xa1/0x110 [ 1108.597249] [<ffffffff8020ef6b>] do_IRQ+0x7b/0x100 [ 1108.597262] [<ffffffff8020c891>] ret_from_intr+0x0/0xa [ 1108.597268] <EOI> [<ffffffff802204e0>] lapic_next_event+0x0/0x10 [ 1108.597315] [<ffffffff8802e6f3>] :processor:acpi_idle_enter_simple+0x162/0x1cb [ 1108.597340] [<ffffffff8802e6e9>] :processor:acpi_idle_enter_simple+0x158/0x1cb [ 1108.597352] [<ffffffff8020b390>] default_idle+0x0/0x40 [ 1108.597365] [<ffffffff803d10a2>] cpuidle_idle_call+0xa2/0xe0 [ 1108.597371] [<ffffffff8020b390>] default_idle+0x0/0x40 [ 1108.597376] [<ffffffff803d1000>] cpuidle_idle_call+0x0/0xe0 [ 1108.597385] [<ffffffff8020b43f>] cpu_idle+0x6f/0xc0 [ 1108.597443] [ 1108.597446] handlers: [ 1108.597449] [<ffffffff8809f300>] (usb_hcd_irq+0x0/0x60 [usbcore]) [ 1108.597483] Disabling IRQ #19 If I suspend to ram then, and wake up, I'll get the Oops: [ 7.988378] Oops: 0000 [1] SMP [ 7.988382] CPU 0 [ 7.988384] Modules linked in: [... stripped, see attachment for details ...] [ 7.988475] Pid: 8293, comm: btdelconn Not tainted 2.6.24-16-generic #1 [ 7.988478] RIP: 0010:[<ffffffff802febc8>] [<ffffffff802febc8>] sysfs_get_dentry+0x38/0xa0 [ 7.988482] RSP: 0018:ffff8100541f9db0 EFLAGS: 00010282 [ 7.988484] RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000000000026 [ 7.988486] RDX: ffff810078eae320 RSI: 0000000000000025 RDI: ffff810070002c30 [ 7.988489] RBP: ffff8100703570d0 R08: 0000000000000023 R09: 0000000000000000 [ 7.988491] R10: 8000000000000000 R11: ffffffff80311760 R12: ffff81005026dbe0 [ 7.988493] R13: 00000000fffffff4 R14: ffff810054109580 R15: 0000000000000000 [ 7.988496] FS: 0000000000000000(0000) GS:ffffffff805b0000(0000) knlGS:0000000000000000 [ 7.988499] CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b [ 7.988501] CR2: 0000000000000008 CR3: 000000007a28c000 CR4: 00000000000006e0 [ 7.988503] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 7.988506] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 7.988508] Process btdelconn (pid: 8293, threadinfo ffff8100541f8000, task ffff810057e247c0) [ 7.988510] Stack: ffff810079fc5140 ffff81003782c8c0 ffff81005026dbe0 ffffffff802fee32 [ 7.988516] 00000000000080d0 ffff810079fc5140 ffff81005e69ccf0 ffff81006024c9c0 [ 7.988520] 00000000fffffff4 ffff810054109580 0000000000000000 ffffffff80344c73 [ 7.988524] Call Trace: [ 7.988532] [<ffffffff802fee32>] sysfs_move_dir+0x52/0x230 [ 7.988546] [<ffffffff80344c73>] kobject_move+0xb3/0x140 [ 7.988559] [<ffffffff803b711a>] device_move+0x6a/0x150 [ 7.988577] [<ffffffff886b0eaa>] :bluetooth:del_conn+0x1a/0x60 [ 7.988587] [<ffffffff886b0e90>] :bluetooth:del_conn+0x0/0x60 [ 7.988592] [<ffffffff8024f21c>] run_workqueue+0xcc/0x170 [ 7.988595] [<ffffffff8024fda0>] worker_thread+0x0/0x110 [ 7.988601] [<ffffffff8024fda0>] worker_thread+0x0/0x110 [ 7.988606] [<ffffffff8024fe43>] worker_thread+0xa3/0x110 [ 7.988612] [<ffffffff80253960>] autoremove_wake_function+0x0/0x30 [ 7.988620] [<ffffffff8024fda0>] worker_thread+0x0/0x110 [ 7.988625] [<ffffffff8024fda0>] worker_thread+0x0/0x110 [ 7.988629] [<ffffffff8025359b>] kthread+0x4b/0x80 [ 7.988637] [<ffffffff8020d198>] child_rip+0xa/0x12 [ 7.988657] [<ffffffff80253550>] kthread+0x0/0x80 [ 7.988662] [<ffffffff8020d18e>] child_rip+0x0/0x12 [ 7.988668] [...] I'll attach my full dmesg for reference. To reproduce this, I basically start bluetooth: > sudo modprobe hci_usb > sudo /etc/init.d/bluetooth restart > gnome-obex-server& and open a serial connection: > sudo rfcomm release 1 > sudo rfcomm bind 1 DE:AD:BE:EF:23:42 > sudo wvdial I'll then do a curlftps or disable wireless, but I dunno whether this relevant for this issue. I'll try the new kernel in a minute. ** Attachment added: "dmesg before suspend to ram" http://launchpadlibrarian.net/14492888/dmesg-bluetooth-oops.txt -- 2.6.24-16-generic Oopses: " comm: btdelconn Not tainted" "Unable to handle kernel NULL pointer dereference at 0000000000000008 RIP:" https://bugs.launchpad.net/bugs/223651 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
