However, while undocking the system seems to work correctly, docking it again causes the following Oops: EIP is at snd_emu10k1_ptr_write+0xb/0x89 [snd_emu10k1] eax: 00000000 ebx: c8194000 ecx: 00000000 edx: 00000019 esi: 00000019 edi: 00000000 ebp: 00000000 esp: cfae1c50 ds: 007b es: 007b ss: 0068 Process kacpid_notify (pid: 11271, threadinfo=cfae1000 task=cfbd6540) Stack: d087b7b4 c8194000 00000000 00000000 00000000 d14f05b0 0000ff00 cf6e3c00 c8194000 d150a31e 00000286 cf6e3c00 00000286 cee77400 cf2f4800 d150b30c cf6e3c00 00000286 d150a06e cee77494 cdef8000 d14f0120 d14f0c2a cf6e3c00 Call Trace: <d14f05b0> free_voice+0x23/0x83 [snd_emu10k1_synth] <d150a31e> snd_emux_terminate_all+0x3b/0x6c [snd_emux_synth] <d150b30c> snd_emux_detach_seq+0xf/0x3b [snd_emux_synth] <d150a06e> snd_emux_free+0x42/0x74 [snd_emux_synth] <d14f0120> snd_emu10k1_synth_new_device+0xf3/0x127 [snd_emu10k1_synth] <d112e0e9> init_device+0x4d/0x82 [snd_seq_device] <d112e28e> find_driver+0xe9/0xf1 [snd_seq_device] <d112e3a3> snd_seq_device_dev_register+0x29/0x35 [snd_seq_device] <d113cbc0> snd_device_register_all+0x20/0x42 [snd] <d113979f> snd_card_register+0xe/0x21b [snd] <d087a5ed> snd_hwdep_new+0xa3/0xb1 [snd_hwdep] <d150bdef> snd_emux_init_hwdep+0x8f/0x9e [snd_emux_synth] <d150a161> snd_emux_register+0xc1/0x10a [snd_emux_synth] <d150a000> sf_sample_new+0x0/0x1e [snd_emux_synth] <d150a01e> sf_sample_free+0x0/0x8 [snd_emux_synth] <d14f0113> snd_emu10k1_synth_new_device+0xe6/0x127 [snd_emu10k1_synth] <d112e0e9> init_device+0x4d/0x82 [snd_seq_device] <d112e28e> find_driver+0xe9/0xf1 [snd_seq_device] <d112e3a3> snd_seq_device_dev_register+0x29/0x35 [snd_seq_device] <d113cbc0> snd_device_register_all+0x20/0x42 [snd] <d113979f> snd_card_register+0xe/0x21b [snd] <d11723a4> snd_card_emu10k1_probe+0x2fd/0x324 [snd_emu10k1] <c01dba41> pci_device_probe+0x36/0x57 <c02281f1> driver_probe_device+0x45/0x9a <c02abc70> klist_next+0x2d/0x36 <c0228246> __device_attach+0x0/0x5 <c0227c1a> bus_for_each_drv+0x32/0x58 <c0228296> device_attach+0x4b/0x5b <c0228246> __device_attach+0x0/0x5 <c0227b42> bus_add_device+0x27/0xcd <c02270ef> device_add+0xcc/0x12d <c01d8a32> pci_bus_add_device+0xb/0x30 <c01d8a6c> pci_bus_add_devices+0x15/0x93 <c01d8aba> pci_bus_add_devices+0x63/0x93 <c01dfdfd> acpiphp_enable_slot+0x2f1/0x3d0 <c02061e0> acpi_ut_update_ref_count+0x4b/0xa0 <c01dfffd> handle_hotplug_event_func+0x6f/0x12f <c01fc1b5> acpi_ex_exit_interpreter+0xa/0x2f <c01f0b54> acpi_evaluate_integer+0x98/0xa2 <c01dff8e> handle_hotplug_event_func+0x0/0x12f <c0209e73> hotplug_dock_devices+0x21/0x79 <c01f0359> acpi_os_execute_thread+0x0/0x1a <c0209f7b> dock_notify+0x7b/0x15d <c0207fc8> acpi_bus_notify+0x17/0x46 <c01f574a> acpi_ev_notify_dispatch+0x49/0x52 <c01f0365> acpi_os_execute_thread+0xc/0x1a <c0124166> kthread+0x91/0xbd <c01240d5> kthread+0x0/0xbd <c0101005> kernel_thread_helper+0x5/0xb Code: e0 21 c2 d3 ea eb 11 9c 59 fa 8b 57 04 89 d8 ef 83 c2 04 ed 89 c2 51 9d 59 89 d0 5b 5e 5f 5d c3 55 89 c5 57 56 89 d6 53 83 ec 04 <83> 78 10 01 8b 7c 24 18 19 c0 83 e1 3f 25 00 00 00 f8 05 00 00 EIP: [<d1177739>] snd_emu10k1_ptr_write+0xb/0x89 [snd_emu10k1] SS:ESP 0068:cfae1c50 ====================================================================== ---------------------------------------------------------------------- tiwai - 06-29-06 18:21 ---------------------------------------------------------------------- This is hard to fix. The driver accesses io to turn off the voices properly at removing while there is no real hardware to access. If it's USB, we have disconnect callback. But for PCI, there is no difference from remove and disconnect.
