Cherche une explication (syslog)

Bonjour !

Pour bien commencer je tiens à vous précisez quelques détails …

Voilà qui est fait ! Maintenant ma question fait référence à un message de “syslog” que j’ai visualisé sur mon terminal:

Message from syslogd@serv-son at Jan 29 15:56:24 ... kernel:[16504.966209] Disabling IRQ #17

Je comprend que ça fait référence à une désactivation du noyau kernel, mais je sait pas à qu’elle processus cela fait référence. Je me suis rendu compte ce matin que je n’avais pas appliqué les bon miroirs à “/etc/apt/sources.list”, maintenant c’est corrigé:

[code]#

deb-src cdrom:[Debian GNU/Linux 6.0.2.1 Squeeze - Official Multi-architecture i386/amd64/source DVD #1 20110626-16:56]/ squeeze main

squeeze-updates, previously known as ‘volatile’

A network mirror was not selected during install. The following entries

are provided as examples, but you should amend them as appropriate

for your mirror of choice.

Pour finir voilà un extrait de “/var/log/syslog”:

[ 2659.102123] No probe response from AP 00:17:33:4b:5e:9c after 500ms, disconnecting. [ 2660.068335] wlan0: direct probe to AP 00:17:33:4b:5e:9c (try 1) [ 2660.265457] wlan0: direct probe to AP 00:17:33:4b:5e:9c (try 2) [ 2660.278219] wlan0: direct probe responded [ 2660.278224] wlan0: authenticate with AP 00:17:33:4b:5e:9c (try 1) [ 2660.477573] wlan0: authenticate with AP 00:17:33:4b:5e:9c (try 2) [ 2660.491037] wlan0: authenticated [ 2660.491063] wlan0: associate with AP 00:17:33:4b:5e:9c (try 1) [ 2660.689183] wlan0: associate with AP 00:17:33:4b:5e:9c (try 2) [ 2660.699601] wlan0: RX AssocResp from 00:17:33:4b:5e:9c (capab=0x411 status=0 aid=1) [ 2660.699605] wlan0: associated

Je pense que ça as un rapport avec la connexion wifi mais en même temps je ne retrouve pas la référence “[16504.966209]” donc j’en suis pas certain. Peut être qu’il y’a une commande qui pourrait m’aider …

Bonjour,

essaye peut-être d’en savoir plus avez :

cat /proc/interrupts

dmesg|grep IRQ

Merci pour la réponse.

J’ai compris ! IRQ 17 c’est le firewire. Merci Nilux.
