[arch] boot lento : exception Emask

[Ecatonchiro]

sto provando arch su un portatile
e durante la sequenza di boot ottengo una trafila enorme
di ata2.00: exception Emask ... che rallentano di molto il boot.

leggendo anche sul forum ufficiale vedo che la cosa e' gia' stata segnalata
e si propone come soluzione l'upgrade del kernel a quello in testing.

Da niubbio di questa ditribuzione (sto proprio iniziandone ora lo studio)
ho provato con un pacman -Syu ma il problema persiste.
(anche perche' penso che in questo modo si sincronizzi solo il gestore di pacchetti)

avete consigli?
e' proprio necessario fare un aggiornamento del kernel?

[ozeta]

mm devi attivare il repository testing.

per farlo devi decommentarlo dalla riga relativa in pacman.conf, poi aggiorni il sistema e ti scaricherà le cose dal testing.

[Ecatonchiro]

no, non va, aggiorna alcuni pacchetti ma non il kernel

PS. per completezza,
le discussioni a cui facevo riferimento prima erano queste
http://bbs.archlinux.org/viewtopic.php?id=35847
http://bbs.archlinux.org/viewtopic.php?id=29043

[ozeta]

mi stampi la versione del kernel? dovrebbe essere inferiore a "kernel26-2.6.23.1-6"

puoi provare l'installazione forzata, mi pare che il comando fosse pacman -F.

[Ecatonchiro]

ciao,
da [pacman -Q kernel26] ottengo la versione 2.6.23.12-3

[manu@2986]

Nel pacman.conf i repository hanno una certa priorità, se infatti metti il repository testing prima di quello core, con pacman -Syu dovrebbe installarti il nuovo kernel senza problemi, ma ti aggiornerebbe anche tutto il resto a testing, che non è molto consigliabile.
Quindi se vuoi installare solo un pacchetto da testing, metti il repository con poca priorità, quindi direi dopo quello community e poi fai pacman -S testing/kernel26.

Spero di essere stato abbastanza chiaro, se hai altri dubbi chiedi pure..

[Ecatonchiro]

ciao chiarissimo ed utile per il mio studio,
ma non per il problema.
La versione del kernel risulta più aggiornata rispetto a quella
incriminata ma nonostante questo continuo ad avere un boot pachidermico.
(al punto che la prima volta che e' partito, non buttando l'occhio ai msg,
mi chiedevo dove diamine fosse la tanto celebrata velocita').

Altro esperimento sarebbe provare il downgrade al vecchio sistema ide.
Ma la cosa non mi entusiasma molto.

[ozeta]

leggendo il secondo topo da te linkato ho trovato questa risposta:

http://bbs.archlinux.org/viewtopic.php?pid=223425#p223425

1) use the earlymodules=piix boot parameter;
2) replace any sd with a hd in menu.lst;
3) replace any sd with a hd in fstab.


il n1) l'ho eseguito anche io a suo tempo, per un problema non dissimile (ma non il tuo, sia chiaro).

già provato a modificare menu.lst?

[Ecatonchiro]

e' che non so come eseguire il punto 1 :B
se avete suggerimenti, son ben accetti

[manu@2986]

e' che non so come eseguire il punto 1 :B
se avete suggerimenti, son ben accetti

credo che basti mettere dentro al file /boot/grub/menu.lst questa riga: earlymodules=piix

[ozeta]

credo che basti mettere dentro al file /boot/grub/menu.lst questa riga: earlymodules=piix

NO! così sballa tutto

deve aggiungere la stringa "earlymodules=piix" in coda alle altre stringhe della stessa riga.

se posta il menu.lst gli faccio vedere dove va inserito

[Ecatonchiro]

ho modificato come segue,
ma non ha funzionato.
Inoltre il fstab commutato da sdax a hdax non viene riconosciuto
e il boot si pianta.
Ovviamente avevo fatto un backup e ora ho ripristinato come sopra

non saprei proprio che dirti :(

[Ecatonchiro]

no problem, ora provo a curare la bronchite,
poi magari posto sul forum di arch
Grazie

[Ecatonchiro]

risolto sul forum di Arch.

Scrivo in caso fosse utile a qualcuno qui

La soluzione, che appunto era già stata segnalata nei link precedenti,
prevede di generare una nuova immagine del kernel in cui si faccia
uso dei vecchi driver ide invece che i nuovi pata.
(Nel mentre mi son letto tutta la letteratura sull'argomento).

Quello che non mi era noto, e che mi ha brasato una installazione,
era il corretto settaggio dei Modules in mkinitcpio.conf per il mio
chipset Ali.

Ecco come fare


1- edita mkinitcpio.conf


MODULES="alim15x3 ata_generic"

HOOKS="base udev autodetect ide keymap filesystems"


2- Cambia in fstab e menu.lst tutti i "sd*" in "hd*",
3- crea una nuova immagine del kernel26


mkinitcpio -p kernel26
