Selon grelaud maurice <grelaud.maurice@wanadoo.fr>:>  kernel: keyboard: Too many NACKs -- noisy kbd cable

Puisque l'on en était à parler de ACK et de NACK; que pensez du log de session
ci-joint en fin de mail?

Les lignes de type     [TCP Dup ACK 8721#1] ftp-data > 1081
semblent être des envois répétitifs du même aquit.
A mon humble avis, ceci pourrait s'expliquer
* par le fait que le paquet à ACKuitter se soit perdu.
   * mal envoyé
   * perdu
   * collision (mais je n'ai pas vu de del s'allumer)

Votre avis?
