[RISOLTO] Udevd timeout in fase di avvio

[nyquist]

Ciao a tutti,
ho una sorta di "non problema" in quanto per ora sembra funzionare tutto. Più che altro è una piccola seccatura. Mi riferisco al fatto che udevd, in fase di avvio, ad un certo punto si ferma e rimane lì per più di 20 secondi, poi dà timeout e la fase di avvio del sistema procede normalmente.
Ho letto che anche altri avevano lo stesso problema (vedi Linux Questions http://www.linuxquestions.org/questions/slackware-14/rc5-long-delay-during-boot-4175428568/).
Penso sia dovuto al modulo ipw2200 della scheda wireless. Su LQ alcuni dicono di aver risolto. Uno, ad esempio, dice di aver risolto aggiungendo il modulo all'initrd. A qualcuno di voi è capitata una cosa smile? Se si, come avete risolto?

[targzeta]

Vedi che su linuxquestion chi pone una domanda, generalmente posta anche qualche informazione più dettagliata? Tipo l'errore segnalato da udev?

Se tu pensi che si possa risolvere inserendo il modulo nell'initrd, perché non provi? Generalmente i problemi di questo tipo si hanno quando un modulo ha bisgono di un firmware esterno che però non trova nella directry /lib/firmware. Però non so se è il tuo caso.

Hai perfettamente ragione. Non ho postato nessun output perchè guardando da alcuni file di log non riuscivo a ricavarne più di tanto,o meglio non sapevo di preciso dove trovare l'output.
Per quanto riguarda il caricamento del modulo in initrd, non l'ho fatto perchè temevo di combinare qualche pasticcio.
Ad ogni modo mi sono buttato (dopo aver letto il man di mkinitrd) e ho risolto dando i comandi:

Codice: Seleziona tutto

mkinitrd -c -k 3.2.29-smp -m ext4:ipw2200 -f ext4 -r /dev/sda2
lilo -t
lilo -v


Ora niente più timeout in fase di avvio e la scheda wireless continua a funzionare correttamente. Quindi sembrerebbe tutto ok.
Ti ringrazio per il consiglio. In futuro cercherò di essere più attento nello scrivere i post.

[targzeta]

Però è strano che tu debba fare un initrd per quei driver. Puoi postare il contenuto dell'initrd? Questo comando dovrebbe funzionare. Eseguilo come utente normale e NON come root, così non potrai fare danni:

Codice: Seleziona tutto

zcat /boot/initrd.gz | cpio -t

[nyquist]

Certo. Ecco l'output del comando:

Vedi che nell'initrd ci sono i firmware necessari alla scheda?

Codice: Seleziona tutto

lib/firmware/ipw2200-sniffer.fw
lib/firmware/ipw2200-bss.fw
lib/firmware/ipw2200-ibss.fw

Non è che hai notato se per caso udev si bloccava perché il driver non riusciva a caricare i firmware? A me sembra strano, perché, generalmente si usa un initrd solo se si deve caricare un driver senza il quale è impossibile andare avanti, oppure si deve configurare lvm, ma per la scheda wireless tutto dovrebbe funzionare senza initrd.

Aspetta un attimo. Faccio un breve riepilogo per chiarezza. Dimmi pure se c'è qualcosa che non ti torna.

Dopo aver installato Slackware 14.0 ho creato l'initrd com ero solito fare con il comando:

Codice: Seleziona tutto

mkinitrd -c -k 3.2.29-smp -m ext4 -f ext4 -r /dev/sda2


Poi ho modificato /etc/lilo.conf così:

Codice: Seleziona tutto

# Linux bootable partition config begins
image = /boot/vmlinuz-generic-smp-3.2.29-smp
  initrd = /boot/initrd.gz
  root = /dev/sda2
  label = 3.2.29
  read-only
image = /boot/vmlinuz
  root = /dev/sda2
  label = Linux
  read-only
# Linux bootable partition config ends


e ho dato

Codice: Seleziona tutto

lilo -t
lilo -v


Da questo punto in poi ho sempre avviato il sistema con il kernel generic.
Sia con il kernel di installazione che con il generic si verificava quel timeout di udevd in fase di boot del sistema. L' "errore" è come quello riportato dall'utente astrogeek nel thread di LQ (vedi link all'inizio).
Poi ho ricreato l'initrd con il comando

Codice: Seleziona tutto

mkinitrd -c -k 3.2.29-smp -m ext4:ipw2200 -f ext4 -r /dev/sda2


Nell'output che seguiva tale comando, verso la fine, ho intravisto delle scritte del tipo

Codice: Seleziona tutto

ADDED /lib/firmware/ipw_qualcosa


Poi ho ridato

Codice: Seleziona tutto

lilo -t
lilo -v


Ecco, solo successivamente, riavviando il sistema, il problema di udevd è scomparso. SInceramente non so il perchè di questa cosa
N.B. Con la 13.37 questo ritardo provocato da udevd in fase di avvio non si verificava
