Bonjour, Après 10 ans d'utilisation de linux me voilà face à mon premier plantage du noyau !
J'ai installé un serveur debian qui fonctionne bien depuis quelques années pour une asso. Je l'administre via ssh et jusqu'à il y a peu il n'avais ni écran ni clavier... L'association à acquis un combiné magnétoscope vhs / graveur dvd et ayant un moniteur et une pctv en rabe j'ai décidé de les monter sur le serveur pour pouvoir "monitorer" l'engin. J'ai monté la carte pctv, mis # defoptions=vga=786 dans mon menu.lst, j'en ai profité pour mettre à jour en 2.6.18-6, installé mplayer et rebooté. Je me suis logué en tant que simple utilisateur (faisant partie du groupe video) et j'ai lancé la commande : ~$ exec mplayer -tv driver=v4l:width=640:height=480:outfmt=i420:device=/dev/video0:input=1 -vc rawi420 -vo fbdev tv:// Nickel, le serveur fait maintenant office de télévision. Ce matin je reçois un appel me disant que le réseau ne fonctionne pas, je tente de me connecter via ssh : "No route to host", je ping la connexion : pas de soucis, je vais voir mes mails logcheck : pas de nouvelles depuis 30 heures ! Donc je vais voir sur place ce qu'il en est : L'écran du serveur affiche bien l'image du magnétoscope ! Le serveur ne répond plus au ping. Le clavier ne répond plus. Les magic SysRq keys ne fonctionnement pas. Le bouton "power" ne répond pas nonplus (normalement ça reboot par acpi) J'ai donc coupé l'alimentation :,((( pour rebooter (le bouton reset n'étant pas branché) et c'est évidemment reparti "comme en 40". Malgré tout je me dis que ça ne devait pas être totalement planté vu que l'image n'était pas figée et que les voyants du clavier ne clignotaient pas (il me semble qu'ils clignotent en cas de kernel panic). altair:~# uname -a Linux altair 2.6.18-6-686 #1 SMP Wed Jan 23 03:23:22 UTC 2008 i686 GNU/Linux altair:~# apt-cache policy mplayer mplayer: Installé : 1.0~rc1-12etch1 Candidat : 1.0~rc1-12etch1 Table de version : *** 1.0~rc1-12etch1 0 990 http://security.debian.org etch/updates/main Packages 990 http://ftp.fr.debian.org etch/main Packages 100 /var/lib/dpkg/status altair:~# grep -C 10 bttv /var/log/syslog Feb 3 01:02:02 altair postfix/qmgr[2831]: 8F9F31A3F: removed Feb 3 01:06:01 altair /USR/SBIN/CRON[21989]: (root) CMD ([ -x /usr/share/mdadm/checkarray ] && [ $(date +%d) -le 7 ] && /usr/share/mdadm/checkarray --cron --all --quiet) Feb 3 01:06:01 altair kernel: md: syncing RAID array md0 Feb 3 01:06:01 altair kernel: md: minimum _guaranteed_ reconstruction speed: 1000 KB/sec/disc.
