Kernel menangguhkan terlalu cepat, setelah melanjutkan melanjutkan tugas menangguhkan

Pembaruan 29 Juni 1919

Dari jawaban yang dihapus di bawah (poster tidak memiliki poin reputasi yang cukup untuk mengirim komentar), laporan bug diajukan di Kernel.org Bugzilla :

• Bug 203791 - s2idle terjadi sebelum proses ruang pengguna dibekukan

Laporan bug lain diajukan di Launchpad :

• Baterai habis saat tidur. Sistem ditangguhkan sebelum kernel menangguhkan semua tugas

21 Okt 1818 Pembaruan

Masalahnya masih ada di sini dan tidak peduli berapa banyak penelitian yang telah saya lakukan (kebanyakan mengulangi penelitian sebelumnya) solusinya tidak lebih dekat. Pengguna lain melaporkan masalah yang sama hari ini: Mode tidur menguras baterai dengan sangat cepat

Singkatnya, Anda dapat melihat journalctl -xelog saya :

Perhatikan bagaimana sistem ditangguhkan 24 Februari pukul 11:30 malam kemudian dilanjutkan kembali pada 25 Februari pukul 7:40 pagi. Setelah melanjutkan sistem segera pergi ke "tidur" dan kemudian "bangun".

Latar Belakang

CATATAN: Dalam Ubuntu 16.04 tutup pengaturan daya diatur ke "Tangguhkan" untuk baterai dan Dicolokkan.

Dalam /etc/systemd/logind.confdefault "abaikan" diubah menjadi HandleLidSwitch=suspenddan HandleLidSwitchDocked=suspend. Alasan mengapa TV eksternal HDMI terhubung dan jika salah satu dari opsi ini (atau pengaturan daya Ubuntu) diatur ke "abaikan" atau "jangan lakukan apa-apa" sistem tetap berjalan ketika tutupnya ditutup tetapi TV menjadi kosong. Di bawah Ubuntu 14.04 (tanpa sistemd) menangguhkan ketika tutupnya ditutup berfungsi seperti yang diharapkan.

Ada banyak bermain-main historis acpi-peristiwa, pm-utils, gnome - ??? dan mungkin dbus - ???. Juga bereksperimen dengan berbagai metode pembekuan pembekuan dan memori.

Sejujurnya saya tidak dapat mengingat semua hal berbeda yang dicoba tetapi sepertinya saya telah mencari semuanya di bawah matahari.

Konten yang relevan dari / var / log / syslog

Melihat pukul /var/log/syslog5:05 pagi sistem ditangguhkan (oleh systemd?). Pada pukul 4:46 sore (16:46) systemd melanjutkan tetapi kemudian kernel membuat laptop tidur dan segera bangun. Ada banyak pesan aneh seperti " induk CPU tidak boleh tidur ".

Kekhawatiran saya adalah hal-hal lain mulai pecah 6 bulan setelah pertanyaan ini awalnya diposting pada Oktober 2016. Misalnya, ethernet tidak tersambung kembali setelah bangun dari penundaan dan wifi mengambil alih. Saya telah menurunkan driver r8169 ke r8168 tetapi hal itu tidak membantu. Saya sudah menyiapkan jaringan restart tetapi itu tidak membantu hal-hal, memang terkadang DNS hilang.

Berikut ini relevan /var/log/syslog:

Apakah ini normal? (Catatan tutup-tutup melakukan hal yang sama kecuali systemd menunda lebih cepat dan melakukan lebih sedikit tugas).

Setelah meninjau semua informasi yang dapat saya temukan, saya sampai pada kesimpulan bahwa Anda terpengaruh oleh bug kernel ini. yang telah mempengaruhi banyak sistem termasuk Asus, Dell, HP, Lenovo, dll. Bug ini yang akan ditandai untuk kedaluwarsa dalam 47 hari jika tidak ada aktivitas lebih lanjut, sangat panas, mencetak 412 pada skor panas bug dan dilaporkan memengaruhi 86 orang pada saat ini. Saya sarankan Anda berlangganan dan memberikan info terkait kernel apa pun yang Anda bisa untuk membantu mengklarifikasi masalah sehingga tetap terbuka dan devs dapat memerasnya.

Kemungkinan solusinya adalah memutakhirkan / kembali ke kernel 4.4.8 seperti yang dicatat di sini dan dikonfirmasi di sini dan di sini.

Pekerjaan telah diminta untuk membalikkan dua bagian kernel tetapi bug saat ini kedaluwarsa sehingga sepertinya para devs tidak mendapatkan semua bantuan yang mereka butuhkan dalam menentukan akar penyebab perilaku ini. Hampir seperti yang saya tahu dari membaca laporan bug masalah ini muncul di kernel 4.4.0, diselesaikan pada 4.4.8 dan kemudian muncul kembali sekitar 4.5.2 tetapi saya tidak akan mengklaim untuk memastikan.

Kemungkinan solusi peningkatan kernel lainnya dilaporkan di sini meskipun saya belum menemukan konfirmasi untuk itu.

Jika Anda menggunakan kernel dari repositori, akan sangat membantu jika Anda meluncurkan ubuntu-bug linuxdari terminal untuk membuat laporan bug baru yang menyediakan informasi spesifik mengenai kernel / masalah Anda.

Anda mungkin ingin mengesampingkan eksekusi yang tidak layak sebagai pelakunya juga. Anda harus dapat melakukan ini dengan menonaktifkan semua kecuali CPU0 seperti:

for x in /sys/devices/system/cpu/cpu*/online; do
  echo 0 >"$x"
done

Anda juga mungkin menemukan informasi ini berguna dalam melacak akar penyebab masalah ini.

Ini adalah masalah khusus yang muncul di dmesg:

PM: Preparing system for sleep (mem)
[...]
PM: Suspending system (mem)

Awalnya coba lakukan:

sudo -H gedit /etc/default/grub

dan atur garis:

GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor"

Parameter lain yang sebelumnya ada di baris ini dapat dibiarkan tidak berubah, yaitu, hanya menambahkan ini kadang-kadang ditunjukkan.

Untuk membuat perubahan efektif, jalankan:

sudo update-grub

Selain itu ada laporan masalah dengan apt-daily.service, yaitu layanan pembaruan berjalan saat boot, yang membuat semuanya berjalan tanpa batas, tidak dapat menyelesaikan.

Coba nonaktifkan layanan:

sudo apt-systemctl disable daily.service # disable run when system boot

Solusi lain yang berhasil bagi saya:

sudo -H gedit /etc/systemd/system.conf

Ubah baris berikut hapus komentar dan pengaturan ke nilai yang masih memungkinkan sistem pemuatan:

# DefaultTimeoutStartSec = 90s
DefaultTimeoutStartSec = 10s
# DefaultTimeoutStopSec = 90s
DefaultTimeoutStopSec = 10s

Catat dmesg jika penyesuaian tidak menghasilkan kegagalan beban dan, jika sesuai, sesuaikan nilainya.

Mengenai komentar ini:

"... Kernel menangguhkan sebagian dan mematikan sistem, tetapi setelah resume selesai menangguhkan dengan segera bangun (tidak ada masalah yang terlihat selain dalam log)"

dan

"Skenario yang sama persis dengan 4.4.8 - Systemd menangguhkan sistem dan setelah melanjutkan Kernel segera tidur dan bangun. Tidak ada yang akan tahu ini terjadi kecuali mereka memeriksa log yang saya posting di atas."

Ini bukan masalah yang sebenarnya dan murni konsekuensi dari ketika output konsol sedang ditangguhkan dan kemudian dilanjutkan tetapi tentu saja mengerikan untuk melihat output buffered yang dihasilkan selama penangguhan benar-benar keluar selama resume.

Untuk keperluan debugging, penangguhan konsol dapat dinonaktifkan:

# echo N > /sys/module/printk/parameters/console_suspend
# cat /sys/module/printk/parameters/console_suspend
N

Kemudian memicu penundaan. Misalnya dengan:

# echo mem > /sys/power/state

Anda akan melihat semua keluaran konsol terkait yang ditangguhkan keluar sebelum melanjutkan persis seperti yang Anda harapkan.
