Ну да, я ж говорю, по тфтп загружается ядро и модуль сетевухи, сетевуха определяется и начинает ДХцепляться, причем снифером видно что ответ от ДХцеплялки приходит.

Потом те сообщения что выше от ядра идут, судя по исходникам ядро не видит опции пришедшей по дхцп с id 17 root path. т.е этот тэг = NULL.
Странные подозрения что виновата опять винда

.

Я так понимаю ядро пытается зацепиться к руту по нфс чтобы взять там фстаб и монтировать уже то что в нем описано :/
