--- Comment #14 from darkbasic <[email protected]> --- Yes, I confirm. I am aware that there is still no Broadwell ucode, but loading (missing) ucode doesn't hurt anyway because it will simply do nothing if there isn't any new ucode available. I just put it to get ready when new ucodes will get released. By the way, did you ever get this i915 trace in dmesg? Sometimes I get it after booting, but this is harmless anyway (it doesn't crash my system): [ 42.350664] ------------[ cut here ]------------ [ 42.350683] WARNING: CPU: 0 PID: 1299 at drivers/gpu/drm/i915/intel_uncore.c:620 hsw_unclaimed_reg_debug+0x6d/0x90 [i915]() [ 42.350685] Unclaimed register detected before reading register 0x223a0 [ 42.350687] Modules linked in: rfcomm cmac ecb ctr ccm bnep nls_iso8859_1 nls_cp437 vfat fat snd_usb_audio snd_usbmidi_lib snd_rawmidi snd_seq_device cdc_ether usbnet r8152 mii btusb btrtl btbcm btintel bluetooth crc16 uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_core v4l2_common videodev media snd_hda_codec_hdmi arc4 nvram msr joydev mousedev iwlmvm iTCO_wdt dell_laptop iTCO_vendor_support dell_wmi hid_multitouch sparse_keymap dcdbas mac80211 intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp evdev input_leds mac_hid kvm_intel iwlwifi kvm psmouse rtsx_pci_ms serio_raw memstick pcspkr cfg80211 dell_led snd_hda_codec_realtek rfkill i2c_i801 lpc_ich snd_hda_codec_generic mei_me i915 mei shpchp wmi battery snd_hda_intel drm_kms_helper snd_hda_codec drm snd_hda_core snd_hwdep intel_gtt [ 42.350740] snd_pcm snd_timer i2c_hid int3403_thermal dw_dmac snd dw_dmac_core snd_soc_sst_acpi gpio_lynxpoint tpm_crb soundcore tpm i2c_designware_platform i2c_algo_bit video processor_thermal_device intel_soc_dts_iosf spi_pxa2xx_platform i2c_designware_core iosf_mbi int3402_thermal 8250_dw int3400_thermal int340x_thermal_zone acpi_thermal_rel acpi_pad ac fan acpi_als thermal kfifo_buf industrialio button processor sch_fq_codel ip_tables x_tables btrfs xor raid6_pq sha256_ssse3 sha256_generic hmac drbg ansi_cprng algif_skcipher af_alg hid_generic usbhid hid dm_crypt dm_mod sd_mod rtsx_pci_sdmmc atkbd libps2 crct10dif_pclmul crc32_pclmul crc32c_intel ghash_clmulni_intel aesni_intel aes_x86_64 lrw gf128mul glue_helper ablk_helper ehci_pci cryptd xhci_pci ehci_hcd ahci xhci_hcd libahci libata scsi_mod [ 42.350784] rtsx_pci usbcore usb_common i8042 serio sdhci_acpi sdhci led_class mmc_core [ 42.350792] CPU: 0 PID: 1299 Comm: akonadi_archive Not tainted 4.2.3-1-ARCH #1 [ 42.350793] Hardware name: Dell Inc.
