[Solved] Installed Arch, I have a kernel problem.

Hi guys, I'm new here, but I use only linux since 2003. I have a problem at boot... When I choose arch from the bootloader I get this:

ERROR: Failed to parse block device name for '/dev/sda6'
ERROR: root fs cannot be detected. Try using the rootfstype= kernel parameter

Or something very very similar. I see that I'm not the only one experiencing this problem so I try solving by myself following hints I've found on this forum... but nothing changed.
I need help

This is what you have to know:

/etc/mkinitcpio.conf:

MODULES=""
HOOKS="base udev autodetect pata keymap filesystems"

I also tried with ide...

fstab

# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0


/dev/cdrom /mnt/cdrom   iso9660   ro,user,noauto,unhide   0      0
/dev/cdrom1 /mnt/cdrom1   iso9660   ro,user,noauto,unhide   0      0
/dev/dvd /mnt/dvd   udf   ro,user,noauto,unhide   0      0
/dev/fd0 /mnt/fd0   vfat   user,noauto   0      0
/dev/sda2 swap swap defaults 0 0
/dev/sda6 / ext3 defaults 0 1

grub entry:

#Archlinux
title           ArchLinux  (on /dev/sda6)
root            (hd0,5)
kernel          /boot/vmlinuz26 root=/dev/sda6
initrd          /boot/kernel26.img
savedefault
boot

Re: [Solved] Installed Arch, I have a kernel problem.

What if you try setting initrd to "/boot/kernel26-fallback.img" or adding "rootfstype=ext3" to the kernel line?

It doesn't help

Re: [Solved] Installed Arch, I have a kernel problem.

That's very curious. I'm just having this problem after installing the lowlatency kernel from this repo:

Server = http://arch.madfire.net/proaudio/i686

So I've just changed the initrd /boot/kernel26.img to /boot/kernel26rt.img and I'm getting exactly the same error. I've also tried changing sda with hda in the grub's menu.lst but nothing changed...

Re: [Solved] Installed Arch, I have a kernel problem.

I forgot to say that my kernel is "kernel26" installed with pacman and that I have two ide maxtor disks..

Have you checked this out:

http://wiki.archlinux.org/index.php/Per … ice_naming

I had to do that a while back to cure similar symptoms.

Re: [Solved] Installed Arch, I have a kernel problem.

I managed to start arch with the fallback kernel, entering /dev/hda6 in grub instead of /dev/sda6... I can't understand why, I'm investigating

Re: [Solved] Installed Arch, I have a kernel problem.

I'm still not able to start arch with the default grub entry. I can just run it with kernel26-fallback.img

Re: [Solved] Installed Arch, I have a kernel problem.

I tried all methods suggested in this topic and I'm not able to start even the fallback kernel...

Re: [Solved] Installed Arch, I have a kernel problem.

Solved running mkinitcpio again from arch (with the fallback kernel). Now arch boots fine.
