Saya memiliki kotak linux debian (Debian Squeeze) yang macet setiap beberapa jam jika saya menjalankan skrip python yang mengendus antarmuka ...
Jejak tumpukan dilampirkan ke bagian bawah pertanyaan ini. Pada dasarnya, saya memiliki antarmuka ethernet Broadcom ( bnx2
driver) yang tampaknya mati ketika saya memulai sesi mengendus dan kemudian mencoba untuk mengirimkan bingkai keluar dari antarmuka yang sama.
Dari apa yang saya tahu, timer pengawas kernel tersandung ...
NETDEV WATCHDOG: eth3 (bnx2): transmit queue 0 timed out
Saya pikir ada cara untuk mengontrol timer pengawas dengan ioctl
(ref: EmbeddedFreak: Cara menggunakan pengawas linux ).
Pertanyaan (Asli):
Bagaimana saya dapat menemukan timer pengawas mana yang mengendalikan eth3? Poin bonus jika Anda dapat memberi tahu saya cara mengganti timer atau bahkan menonaktifkan ...
Pertanyaan (Direvisi):
Bagaimana saya bisa mencegah pengawas waktu ethernet dari menyebabkan masalah?
