Saya melakukan upgrade penuh pada sistem Debian saya (jessie / sid). Sayangnya sekarang ada celah 30 detik pada bootup dan saya benar-benar tidak tahu dari mana asalnya dan di mana saya harus mencari untuk menemukannya.
Saya melihat /var/log/dmesgdan menemukan beberapa baris yang bisa menarik. Perhatikan celah antara 27.280227dan 56.835253.

Mencari [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp offpoin ke beberapa bug grafis. Karena saya terkadang mengalami masalah dengan kartu grafis saya (kartu grafis yang dapat diganti), ini bisa menjadi alasan.

Seperti yang saya katakan, saya tidak tahu ke mana harus mencari dan apa yang harus dicari. Saya juga senang dengan beberapa kata kunci yang mungkin membantu.
Saya harap saya memberikan informasi yang Anda butuhkan. Jika tidak, alangkah baiknya jika Anda juga dapat memberi tahu saya perintah mana yang harus saya jalankan untuk mendapatkan output yang Anda inginkan, karena saya masih belum terlalu akrab dengan 'sistem yang lebih dalam'.
Terima kasih banyak,
