This is with the top of the tree at f7813ad5cbfd as mentioned in the subject. The machine has an HDMI port, but it is not connected to any thing. josh [ +0.005071] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC283: line_outs=1 (0x21/0x0/0x0/0x0/0x0) type:hp [ +0.000009] snd_hda_codec_realtek hdaudioC0D0: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) [ +0.000005] snd_hda_codec_realtek hdaudioC0D0: hp_outs=0 (0x0/0x0/0x0/0x0/0x0) [ +0.000003] snd_hda_codec_realtek hdaudioC0D0: mono: mono_out=0x0 [ +0.000004] snd_hda_codec_realtek hdaudioC0D0: inputs: [ +0.000006] snd_hda_codec_realtek hdaudioC0D0: Mic=0x19 [ +0.323524] ------------[ cut here ]------------ [ +0.000019] WARNING: CPU: 0 PID: 550 at sound/hda/hdac_i915.c:129 snd_hdac_acomp_get_eld+0x53/0x70 [snd_hda_core]() [ +0.000004] Modules linked in: snd_hda_codec_hdmi(+) cfg80211 snd_hda_codec_realtek snd_hda_codec_generic btusb btrtl lpc_ich i2c_i801 snd_hda_intel snd_hda_codec mei_txe snd_hda_core snd_hwdep mei snd_intel_sst_acpi snd_intel_sst_core snd_soc_rt5640 snd_soc_sst_mfld_platform snd_soc_rl6231 ir_lirc_codec lirc_dev snd_soc_sst_match snd_soc_core rc_rc6_mce snd_compress ite_cir snd_pcm_dmaengine rc_core ac97_bus snd_seq snd_seq_device hci_uart dw_dmac snd_pcm btbcm dw_dmac_core btqca btintel bluetooth snd_timer snd rfkill_gpio soundcore rfkill i2c_designware_platform i2c_designware_core spi_pxa2xx_platform tpm_tis tpm i915 r8169 serio_raw mii i2c_algo_bit drm_kms_helper drm video fjes sdhci_acpi i2c_hid sdhci mmc_core [ +0.000086] CPU: 0 PID: 550 Comm: modprobe Tainted: G W 4.6.0-0.rc0.git11.1.fc25.x86_64 #1 [ +0.000003] Hardware name: \xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff \xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff\xffffffff/DN2820FYK, BIOS FYBYT10H.86A.0034.2014.0513.1413 05/13/2014 [ +0.000004] 0000000000000286 000000001953c40f ffff880233c679c0 ffffffff81454ea5 [ +0.000007] 0000000000000000 ffffffffc0465eea ffff880233c679f8 ffffffff810b2912 [ +0.000006] ffff88023308b000 ffff8800b804a000 ffff880233fa3800 ffff8800b804a330 [ +0.000005] Call Trace: [ +0.000008] [<ffffffff81454ea5>] dump_stack+0x86/0xc1 [ +0.000007] [<ffffffff810b2912>] warn_slowpath_common+0x82/0xc0 [ +0.000005] [<ffffffff810b2a5a>] warn_slowpath_null+0x1a/0x20 [ +0.000009] [<ffffffffc0463f53>] snd_hdac_acomp_get_eld+0x53/0x70 [snd_hda_core] [ +0.000009] [<ffffffffc04f99ae>] hdmi_present_sense+0xae/0x3a0 [snd_hda_codec_hdmi] [ +0.000007] [<ffffffffc04fa0b0>] generic_hdmi_build_controls+0x150/0x1f0 [snd_hda_codec_hdmi] [ +0.000014] [<ffffffffc048bcec>] snd_hda_codec_build_controls+0x1bc/0x200 [snd_hda_codec] [ +0.000011] [<ffffffffc0486450>] hda_codec_driver_probe+0x80/0x100 [snd_hda_codec] [ +0.000006] [<ffffffff815b0b10>] ?
