質問: ubuntu 16.04ラップトップがぶら下がっていて、パワーサイクルが必要です ubuntu16.04を実行している新しいdellinspironラップトップが予期せずぶら下がっているという奇妙な状況が発生しており、その理由がわからないようです。私はそれを引き起こす一貫した行動を観察していません。何が起こるかというと、ウィンドウシステム(gnomeを使用)がフリーズし、マウスアクションがなく、キーボードからの応答がなく、シェルにドロップできないなどです。そのため、ハードパワーサイクルを実行して元に戻すしかありません。私がこれまでに観察した唯一の一貫性は、これは画面がロックされているときにマウスを動かしたとき、または画面のロックを解除した直後(<30秒)に常に発生するように見えることです。syslogで問題の可能性を調べると、警告が表示されることがありますが、これらの警告は、マシンがロックされていないときにも発生します。これが発生した最新の時刻の直前の時刻については、syslogのセクションについて以下を参照してください。ただし、ログのこのセクションは、実際に画面のロックを解除してハング動作に遭遇する前のものです。実際の問題の時点では、ログには何もありません。私は経験豊富なシステム管理者ですが、ラップトップでubuntuを実行するのは初めてです。この問題は、何が問題になっているのかを理解しようとする私の試みを苛立たせています。誰かが私が何が悪いのかを追跡するのを手伝ってくれることを願っています。may 25 11:40:22 femur kernel: [95510.664099] ------------[ cut here ]------------ may 25 11:40:22 femur kernel: [95510.664187] warning: cpu: 0 pid: 1468 at /build/linux-fvchlk/linux-4.4.0/ubuntu/i915/intel_pm.c:3572 skl_update_other_pipe_wm+0x16c/0x180 [i915_bpo]() may 25 11:40:22 femur kernel: [95510.664193] warn_on(!wm_changed) may 25 11:40:22 femur kernel: [95510.664198] modules linked in: drbg ansi_cprng ctr ccm ipt_masquerade nf_nat_masquerade_ipv4 rfcomm iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 xt_addrtype iptable_filter ip_tables xt_conntrack x_tables nf_nat nf_conntrack br_netfilter bridge stp llc aufs bnep arc4 iwlmvm mac80211 snd_soc_skl snd_soc_skl_ipc snd_hda_ext_core intel_rapl snd_soc_sst_ipc snd_soc_sst_dsp btusb hid_sensor_rotation x86_pkg_temp_thermal snd_soc_core btrtl iwlwifi intel_powerclamp kvm_intel snd_hda_codec_hdmi snd_compress hid_sensor_magn_3d hid_sensor_incl_3d hid_sensor_gyro_3d ac97_bus snd_hda_codec_conexant snd_pcm_dmaengine hid_sensor_accel_3d snd_hda_codec_generic hid_sensor_als dw_dmac_core hid_sensor_trigger industrialio_triggered_buffer hid_sensor_iio_common joydev snd_hda_intel snd_hda_codec cfg80211 kvm snd_hda_core hid_multitouch snd_hwdep i2c_designware_platform i2c_designware_core snd_pcm dell_wmi sparse_keymap snd_seq_midi dell_laptop irqbypass snd_seq_midi_event dcdbas snd_rawmidi crct10dif_pclmul dell_smm_hwmon snd_seq crc32_pclmul snd_seq_device snd_timer aesni_intel hci_uart aes_x86_64 snd lrw gf128mul glue_helper ablk_helper btbcm cryptd btqca idma64 btintel mei_me soundcore virt_dma processor_thermal_device bluetooth mei intel_soc_dts_iosf shpchp intel_lpss_pci input_leds serio_raw soc_button_array acpi_als dell_smo8800 intel_lpss_acpi int3403_thermal int3402_thermal intel_lpss int340x_thermal_zone kfifo_buf int3400_thermal acpi_thermal_rel industrialio tpm_crb acpi_pad mac_hid uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_core v4l2_common videodev media coretemp parport_pc ppdev lp parport autofs4 hid_sensor_custom hid_sensor_hub hid_generic usbhid i915_bpo intel_ips i2c_algo_bit drm_kms_helper psmouse syscopyarea sysfillrect sysimgblt fb_sys_fops ahci drm libahci i2c_hid wmi hid pinctrl_sunrisepoint video pinctrl_intel fjes may 25 11:40:22 femur kernel: [95510.664475] cpu: 0 pid: 1468 comm: xorg tainted: g w 4.4.0-22-generic #40-ubuntu may 25 11:40:22 femur kernel: [95510.664481] hardware name: dell inc. inspiron 13-7359/03dmwj, bios 01.00.00 08/07/2015 may 25 11:40:22 femur kernel: [95510.664487] 0000000000000286 00000000c5fb32c1 ffff8802625d7938 ffffffff813e9c53 may 25 11:40:22 femur kernel: [95510.664497] ffff8802625d7980 ffffffffc0261c70 ffff8802625d7970 ffffffff81080fb2 may 25 11:40:22 femur kernel: [95510.664505] ffff8802686a3000 ffff880262a89d9c ffff8802686a4000 ffff8802630a6378 may 25 11:40:22 femur kernel: [95510.664515] call trace: may 25 11:40:22 femur kernel: [95510.664553] [<ffffffff813e9c53>] dump_stack+0x63/0x90 may 25 11:40:22 femur kernel: [95510.664566] [<ffffffff81080fb2>] warn_slowpath_common+0x82/0xc0 may 25 11:40:22 femur kernel: [95510.664575] [<ffffffff8108104c>] warn_slowpath_fmt+0x5c/0x80 may 25 11:40:22 femur kernel: [95510.664641] [<ffffffffc01935cc>] skl_update_other_pipe_wm+0x16c/0x180 [i915_bpo] may 25 11:40:22 femur kernel: [95510.664702] [<ffffffffc0193766>] skl_update_wm+0x186/0x5f0 [i915_bpo] may 25 11:40:22 femur kernel: [95510.664794] [<ffffffffc021f36f>] ?

回答: これはハードウェアの問題である可能性が非常に高いです。新しいハードウェアで2回、新しいマザーボードで1回、新しいラップトップで1回、同様の問題が発生しました。新しいハードウェアを購入すると、それが飛ぶことを期待し、フリーズし始めたとき-4回目または5回目の再起動後、ウィンドウからそれを投げる準備ができています。 :)マザーボードの問題は新しいbiosファームウェアで解決され、ラップトップの問題は障害のあるメモリの変更によりサービス中に解決されました。時間とエネルギーがあり、ハードディスク(または予備の外付けドライブ)に予備のパーティションがある場合は、windowsのインストールを試すことができます。問題はドライバーにある可能性があるため、ハードウェアに障害がある必要はありません。2〜3日後にwindowsが正常に動作する場合は、無効にできるbiosハードウェア(グラフィックカードなど)で無効にしようとしたり、他のカーネルバージョン(新しいまたは古い)を使用したり、一部のドライバーを無効にしたりできます。このようなタスクは複雑であることは承知していますが、ハードウェアの問題を推測/デバッグすることは、経験豊富なユーザーや専門家の仕事です。編集:最近のdellラップトップは非常にlinuxに対応しているため(linuxとラベル付けされた一連のxpsまたはinspironが内部にあるなど)、最近のカーネルとディストリビューション(ubuntu 1604は先月公開されました)と新規インストール問題なく動作するはずです。これは喜んで読んでいただける情報ではないことは承知しておりますが、(新しいハードウェアの故障)と思われる可能性は低いため、考えずに破棄してはならない可能性があります。私はあなたを怖がらせるためではなく、あなたの問題の解決を早めるためにこれを書いています。私が同じような状況にあったときに私がどのように惨めに感じたかをよく覚えています。
