pata & modules in mkinitcpio.conf and rc.conf [solved]

DonVla · 2008-01-23 14:39:50

hello,

last year when i installed arch i used the ide-legacy module for my ide stuff, because of compatibility reasons (my hardware is quite old: mainboard 7 years, hdd 3 years, cdrom 5 years). i wanted yesterday to switch to pata. i changed following files: menu.lst, fstab and finally mkinitcpio.conf, ran "mkinitcpio -g kernel26pata.img" like described in a thread here (http://bbs.archlinux.org/viewtopic.php?id=32296).
here are the relevant entries:
fstab:

/dev/sda5               /                           reiserfs        defaults           0      1
/dev/sda1               /boot                       ext3            defaults           0      2
/dev/sda6               /var                        reiserfs        defaults           0      2
/dev/sda4               /home                       reiserfs        defaults           0      2
/dev/sda3               none                        swap            sw                 0      0

menu.lst:

# (0) Arch Linux
title  Arch Linux
root   (hd0,0)
kernel /vmlinuz26 root=/dev/sda5 resume=/dev/sda3 ro vga=773
initrd /kernel26pata.img

and finally mkinitcpio.conf:

MODULES="generic via82cxxx"
HOOKS="base udev autodetect pata filesystems"

note that the MODULES array is the one automatically generated at installation.
and for the sake of completeness here are also some relevant entries from rc.conf:

MOD_AUTOLOAD="yes"
MODULES=(8139cp 8139too mii slhc ac97_bus snd-mixer-oss snd-pcm-oss snd-seq-oss snd-seq-device snd-seq-midi-event snd-seq snd-hwdep snd-page-alloc snd-pcm snd-rawmidi snd-timer snd snd-ac97-codec snd-emu10k1 snd-bt87x soundcore snd-util-mem i2c-viapro w83781d via686a lirc_sir fuse truecrypt joydev)
DAEMONS=(syslog-ng hal @network @netfs sshd @gpm @crond @adsl @alsa @anacrond dovecot postfix lircd privoxy tor)

here the same: the MODULES array is the one generated at installation. i only added the last four.

however, everytime i wanted to boot into arch the hdd and cdrom was detected as hd* not sd* and further booting failed because of the fstab entries (messages like: unable to detect /dev/sda5 etc). obviously the ide modules still get loaded instead of the pata ones.

now i'm clueless. what did i do wrong?
is there a way to automagically generate the MODULES array in mkinitcpio.conf, so the pata-hook affects?
i don't really want to edit this by hand or do this by try-and-error.

and another question: when i change my hardware (let's say i use another soudcard with another module), is there a way to regenerate the MODULES array in rc.conf?
i know i can use hwdetect --modules, but this shows about 70 modules.

some more information:

I'd say throw ata_generic and pata_via in your modules line for mkinitcpio.conf

DonVla · 2008-01-23 19:02:02

thanks,

which modules do i need now:
ata_generic, pata_via... and?
i guess i don't need generic any more, but via82cxxx? that's the module for the chipset.
as i asked before

is there a way to automagically generate the MODULES array in mkinitcpio.conf, so the pata-hook affects?

i mean, it _was_ automatically generated at installation.

You often don't need anything at all in the MODULES= entries (both mkinitcpio.conf and rc.conf) - only stuff that doesn't get autodetected. I would suggest you start with nothing, rerun mkinitcpio and add anything that's missing later. Soundcards often get autodetected, so you might not need them in the MODULES array. You should also check that there's nothing harmful in /etc/modprobe.conf.

DonVla · 2008-01-24 16:50:21

thanks,
i got it working.

MODULES="pata_via ata_generic"

in mkinitcpio.conf did the trick.
@gradgrind: when i have some time i'll try your suggestion and tweak the conf file entries. but when i installed arch i intended to tweak and change stuff as less as possible.
btw, what do you mean by "check that there's nothing harmful in /etc/modprobe.conf." what could be harmful?

Glad it's going now.

Nothing specific. It's just that it's one of those places where old configurations which are perhaps no longer valid could gather.

DonVla · 2008-01-24 17:38:51

yes, i see.

two last questions for clarity:
when i run mkinitcpio -M i get a list of modules. can i put them into the MODULES list in mkinitcpio.conf and delete the autodetect and filesystems hooks? and can i use the hwdetect --modules output for the MODULES array in rc.conf?

According to this article in the wiki, YES.: http://wiki.archlinux.org/index.php/Ude … _One_Thing

DonVla · 2008-01-25 15:39:56

thanks misfit138,

and what about the mkinitcpio.conf MODULES entry.
