Problema montaggio cdrom

[Neptune]

Mi sono accorto solo ora (è da un pò di tempo che non infilo un cdrom) che non mi funzioan il cdrom.
Se do il comando "mount /dev/cdrom" mi appare scritto:

mount: special device /dev/cdrom does not exist

Ho controllato in /dev e pare che non esista proprio "cdrom" eppure nell'fstab ci sta scritto:

/dev/cdrom                                    /media/cdrom                   udf,iso9660     noauto,ro,users                            0      0

Ho provato a dare un dmesg è questo il risultato: (ve lo inserisco in un'altro messaggio o il post è troppo lungo)[..]

Dove nello specifico sembra rilevarmi il cdrom su hdb:

hdb: _NEC DVD_RW ND-3520A, ATAPI CD/DVD-ROM drive

Questo signfiica che i moduli del cdrom sono caricati correttamente giusto? perchè l'unico dubbio che mi era venuto è che ho ricompilato il kernel e quindi magari "non me li avesse caricati".

Altro dubbio è che sto utilizzando virtualbox-ose, che ha montato un iso dall'hd e che sta installando dall'iso, può essere per quello che invece non mi va?

Vi ringrazio in anticipo per l'aiuto,
Neptune.

Io butterei anche un'occhio sulle ultime righe dove dice "warning: 'virtualbox.....", che significa?

[Neptune]

Ho riavviato sul kernel precompilato da sidux ed invece va il cdrom, ergo non ho aggiunto il modulo per il cdrom nel momento della compilazione? come faccio ad aggiungerlo ora?

Mi sono accorto, dano make menuconfig, che "include ide/atapi cdrom support" era deselezionato, lo selezionato come modulo e poi ho dato make-kpkg --append_to_version -486 --initrd --revision=rev.03 modules_image però mi ha compilato solo il modulo di virtualbox e non mi ha creato nessun pacchetto riguardo il cdrom. C'è bisogno di dargli un "make-kpkg clean" per fargli prendere il nuovo file di configurazione? oppure dov'è che sbaglio?

c'è di sicuro qualche opzione sballata nella configurazione del kernel, visto che (ad occhio) c'è un po' di confusione direi di procedere in questo modo:

prima di qualsiasi altra cosa

$ make-kpkg clean

nella dir dei sorgenti

successivamente controlla che queste opzioni siano presenti nella config
gli output sono a titolo di esempio, è per farti capire le impostazioni basilari, ovviamente nel caso sistemale per le tue necessità

$ cat /boot/config-`uname -r` | grep CONFIG_BLK_DEV_IDE
# CONFIG_BLK_DEV_IDE_SATA is not set
CONFIG_BLK_DEV_IDECD=y
CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS=y
CONFIG_BLK_DEV_IDETAPE=m
# CONFIG_BLK_DEV_IDESCSI is not set
# CONFIG_BLK_DEV_IDEACPI is not set
CONFIG_BLK_DEV_IDEPNP=y
CONFIG_BLK_DEV_IDEDMA_SFF=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_BLK_DEV_IDEDMA=y

$ cat /boot/config-`uname -r` | grep CONFIG_ISO9660_FS
CONFIG_ISO9660_FS=m

con questo in teoria dovresti essere a posto, eventualmente fai un diff tra il kernel funzionante e quello che da problemi, li sicuramente rintracci l'inghippo.

edit:
devi ricompilare il tutto naturalmente, puoi usare make-kpkg in ambiente fakeroot (come già sai) una cosa del genere

$ fakeroot make-kpkg --revision=0.1 --append-to-version -neptune kernel_image

Ho risolto, mancava solo guardacaso il modulo per il supporto del cdrom, "include ide/atapi cdrom support", mi chiedo come ho fatto a dimenticarmi proprio quel modulo il cui utilizzo è tanto chiaro
