Kesalahan perangkat keras CPU di Ubuntu 17.04

12

Adakah yang bisa menjelaskan kepada saya apa pesan kesalahan ini yang saya dapatkan ketika saya mencari di dmesg? Saya baru mengenal Ubuntu dan Dunia Linux.

Saya menjalankan Ubuntu 17.04 dengan 4.10.0-29-generic kernal

atau itu adalah bug perangkat lunak yang saya miliki memiliki log yang sama di Lenovo T480S baru saya lihat bugs.launchpad.net/ubuntu/+source/linux/+bug/1781924

CPU kepanasan dan pergi ke MCE (peristiwa mesin periksa) ... yaitu: itu crash. Jika Anda tidak melihat acara terkait suhu lainnya di syslog, itu mungkin karena pendingin CPU / kipas / pipa termal / pasta termal Anda tidak melakukan pekerjaan.

  • Periksa syslog dengan terminalperintah ini ...

    grep -i -e temp -e therm /var/log/syslog*
    
  • Jika mesin sangat kotor / berdebu, itu bisa memainkan peran utama dalam mesin kepanasan. Bersihkan itu.

  • Jika mesin Anda memiliki prosesor Intel, pastikan intel-microcodesudah terpasang.

    sudo apt-get update
    sudo apt-get install intel-microcode
    reboot
    
  • Instal thermalduntuk mencoba dan mengontrol suhu.

    sudo apt-get update
    sudo apt-get install thermald
    reboot
    
  • Periksa versi BIOS Anda. Masukkan BIOS Anda tepat waktu, dan perhatikan versi #. Pergi ke situs web produsen dengan membuat / model komputer Anda. Buka bagian dukungan / unduhan, dan lihat apakah ada BIOS yang lebih baru.

  • Terakhir, dan sangat mungkin, jika ini adalah mesin yang lebih tua, senyawa termal yang berada di antara prosesor dan pipa panas / pendingin kipas perlu diterapkan kembali. Ini membutuhkan beberapa pengalaman teknis.

Apa dampaknya intel-micorocodeterhadap suhu?
gene_wood
@ gen_wood seperti yang saya sebutkan, itu mungkin masalah debu, kipas, atau senyawa termal, dan memeriksa mikrokode hanyalah langkah lain dalam membantu mendiagnosis masalah dari jarak jauh. Mikrokode lama CPU yang berjalan dapat menyebabkan berbagai masalah. Detik untuk memeriksanya.
