Ho terminato l'installazione ma al primo boot mi si presenta il problema riportato nel titolo,come risolvo?
(Perché non ho tenuto l'installazione funzionante? :cry: :cry: )
Contenuto /boot/grub/grub.conf (non uso initramfs):
Code:

default 0
timeout 5
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title Gentoo Linux 3.16.5
root (hd0,0)
kernel /boot/kernel-3.16.5 root=/dev/sda3


Output lspci:

Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x0005f20d

   Device Boot      Start         End      Blocks   Id  System

/dev/sda3         1116160   976773167   487828504   83  Linux


Durante il boot appare anche scritto ATA 0.2 unable to identify .... o qualcosa di simile ma da lspci non vedo nessun ATA,semmai SATA.Nel kernel il supporto ATA/ATAPI è disabilitato.

Ho risolto ricompilando il kernel con genkernel e aggiornando grub.conf ......credo che il kernel panico fosse dovuto a una mancanza nel kernel.

Si, se manca un driver nel kernel che è vitale per l'avvio del sistema allora ti si presenta un kernel panic.

Odio genkernel! Ha prodotto un kernel pieno di moduli inutili e non ha abilitato il supporto per le schede wireless Atheros ath9k.Meglio il classico make menuconfig,anche se non sembra funzionare in questo caso.

genkernel utilizzato con le dovute opzioni :
Code:
# genkernel  <opzioni> <opzioni> <...> --menuconfig all


e ti configuri quello che serve

se lo esegui senza parametri utilizza una versione del config di default.

Code:
# man genkernel
