![]() The HDA codec driver issues snd_hda_codec_reset() at the error path of PCM build. This was needed in the earlier code base, but the recent rewrite to use the standard bus binding made this a deadlock: modprobe D 0000000000000005 0 720 716 0x00000080 Call Trace: [<ffffffff816a5dbe>] schedule+0x3e/0x90 [<ffffffff816a61a5>] schedule_preempt_disabled+0x15/0x20 [<ffffffff816a7ae5>] __mutex_lock_slowpath+0xb5/0x120 [<ffffffff816a7b6b>] mutex_lock+0x1b/0x30 [<ffffffff8148656b>] device_release_driver+0x1b/0x30 [<ffffffff81485c15>] bus_remove_device+0x105/0x180 [<ffffffff814822b9>] device_del+0x139/0x260 [<ffffffffa05e0ec5>] snd_hdac_device_unregister+0x25/0x30 [snd_hda_core] [<ffffffffa074fa6a>] snd_hda_codec_reset+0x2a/0x70 [snd_hda_codec] [<ffffffffa075007b>] snd_hda_codec_build_pcms+0x18b/0x1b0 [snd_hda_codec] [<ffffffffa074a44e>] hda_codec_driver_probe+0xbe/0x140 [snd_hda_codec] [<ffffffff81486ac4>] driver_probe_device+0x1f4/0x460 [<ffffffff81486dc0>] __driver_attach+0x90/0xa0 [<ffffffff81484844>] bus_for_each_dev+0x64/0xa0 [<ffffffff814862de>] driver_attach+0x1e/0x20 [<ffffffff81485e7b>] bus_add_driver+0x1eb/0x280 [<ffffffff81487680>] driver_register+0x60/0xe0 [<ffffffffa074a0da>] __hda_codec_driver_register+0x5a/0x60 [snd_hda_codec] [<ffffffffa070a01e>] realtek_driver_init+0x1e/0x1000 [snd_hda_codec_realtek] [<ffffffff810002f3>] do_one_initcall+0xb3/0x200 [<ffffffff816a1fc5>] do_init_module+0x60/0x1f8 [<ffffffff810ee5c3>] load_module+0x1653/0x1bd0 [<ffffffff810eed48>] SYSC_finit_module+0x98/0xc0 [<ffffffff810eed8e>] SyS_finit_module+0xe/0x10 [<ffffffff816aa032>] entry_SYSCALL_64_fastpath+0x16/0x75 The simple fix is just to remove this call, since we don't need to think about unbinding at there any longer.
