Sistem Debian 9 saya bangun dalam 2-5 detik setelah masuk ke mode tidur (menangguhkan ke RAM) secara manual atau otomatis. Masalahnya selalu terjadi tidak peduli bagaimana mode tidur dipanggil: dengan tutup tutup, dengan tombol power, atau dari terminal. Apa yang bisa menjadi masalah?
Ini adalah info sistem:
$ sudo dmidecode | grep -A3 '^System Information'
System Information

$ uname -a
Linux 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u5 (2017-09-19) x86_64 GNU/Linux
Untuk memeriksa perangkat mana yang dapat menyebabkan masalah, saya memeriksa /proc/acpi/wakeupdan menonaktifkan setiap perangkat untuk sementara waktu dengan mengeluarkan echo DeviceName > /proc/acpi/wakeup, tetapi masalahnya masih berlanjut. Ini dia sebelum saya berubah:
$ cat /proc/acpi/wakeup

breakparameter kernel, dan ketika Anda terjatuh saat(initramfs)diminta, lakukanecho mem >/sys/power/stateuntuk menangguhkan mesin Anda. Jika itu berhasil, coba temukan titik yang memecahnya: misalnyaacpidberinteraksi dengansystemd-logind(boot dengansystemd.unit=rescue.target), dengan manajer display Anda (boot dengansystemd.unit=multi-user.target) atau dengan manajer daya desktop Anda (tutup lingkungan desktop Anda).Jawaban:
Saya tidak tahu apakah Anda pernah menyelesaikan masalah ini, tetapi saya mengalami hal yang sama terjadi pada Debian buster / sid pada ThinkPad T460. Keluaran saya
dmesgtidak identik dengan milik Anda, tetapi yang penting, hasilnya samabaris. Per utas ini di AskUbuntu , saya menonaktifkan XHCI sebagai pemicu bangun di
/proc/acpi/wakeup:dan itu memperbaikinya bagi saya. Anehnya, ini seharusnya hanya masalah jika Anda memiliki perangkat USB dicolokkan ke mesin, tapi saya pasti tidak.
EDIT: Sudahlah, saya lupa tentang bagian di mana Anda mencoba menonaktifkan setiap baris
/proc/acpi/wakeup.sumber
XHCyang menyebabkan masalah (ThinkPad T470s, Ubuntu 16.04, kernel 4.15).Masalah terpecahkan. Entah bagaimana itu keyboard. Salah satu kunci F saya rusak dan saya memutuskan untuk menguji apakah kunci ini terus-menerus mengirim input. Lalu saya menguji input keyboard di terminal - tidak ada input yang ditampilkan ketika saya tidak menyentuh keyboard. Meskipun begitu, ketika saya mengganti keyboard dengan yang baru, saya bisa membuat PC tidur. Mungkin itu sesuatu yang berkaitan dengan Thinkpad BIOS, saya kira, karena apa pun yang saya coba di OS, saya tidak dapat melihat input keyboard yang mungkin membangunkannya dari tidur.
