Grub hangs when booting kernel [SOLVED]

I just installed Arch using the 2009.08 net install i686 isolinux CD.

Upon booting, the grub menu shows up fine. However, after I select the kernel to boot it hangs at:

Booting 'Arch Linux'
root (hd0,1)
 Filesystem type is ext2fs, partition type 0x83
 kernel /vmlinuz26 root=/dev/mapper/VolGroup00-lvolroot ro
    [Linux-bzImage, setup=0x3400, size=0x1b4370]

I've let it sit there for about 30 mins and it doesn't move. I'm not sure what's going on....

Here is my fdisk -l output:

Disk /dev/sda: 80.0 GB, 80000000000 bytes

Relevant Ouput of /boot/grub/menu.lst:

# (0) Arch Linux
title  Arch Linux
root   (hd0,1) # First Hard Drive Second Partition
kernel /vmlinuz26 root=/dev/mapper/VolGroup00-lvolroot ro
initrd /kernel26.img

# (1) Arch Linux
title  Arch Linux Fallback
root   (hd0,1)
kernel /vmlinuz26 root=/dev/mapper/VolGroup00-lvolroot ro
initrd /kernel26-fallback.img

I also made sure that in my /etc/rc.conf USELVM="yes"
Additionally, the HOOKS section in my /etc/mkinitcpio.conf contains lvm2

The fallback also doesn't work either sad

I've also tried regenerating the initramfs (using my PartedMagic Live USB and chrooting into arch) with:

/sbin/mkinitcpio -g /boot/kernel26.img -k 2.6.16-ARCH

I'm not sure where to go from here...

If it helps, here is my computer info:

***Computer***
Processor        : 2x Intel(R) Pentium(R) 4 CPU 3.00GHz

***IDE Disks***

Any help is appreciated.

This struck me as a bit odd (the kernel version string in particular). Try `mkinitcpio -p kernel26'.

I got it from http://wiki.archlinux.org/index.php/Mkinitcpio#Manually

In there it states:

If you are creating an image for a kernel other than the one you are currently running, add the kernel version to the command line:
mkinitcpio -g /boot/kernel26.img -k 2.6.16-ARCH

The reason is because I am booted into a PartedMagic Live USB and then chrooted into my arch install.

I will try what you stated and post the results.

Re: Grub hangs when booting kernel [SOLVED]

Running mkinitcpio -p kernel26 outputs SUCCESS but when I reboot I get to the same spot and it still hangs sad even for the fallback too

Re: Grub hangs when booting kernel [SOLVED]

I've admittedly only glanced at your post, but the kernel line in grub seems odd. Perhaps that is the right way of addressing volumes in LVM setups, but perhaps you want to try and find the kernel within grub and take it from there.

never trust a toad...

I got the kernel line from here:

http://wiki.archlinux.org/index.php/LVM#Important

It says:

Make sure /boot/grub/menu.lst uses the right volumes for root. It should look something like this: (Install Bootloader)
...
# (0) Arch Linux
title  Arch Linux
root   (hd0,0)
kernel /vmlinuz26 root=/dev/mapper/VolGroup00-lvolroot resume=/dev/mapper/VolGroup00-lvolswap ro
initrd /kernel26.img
...

I also tried a similar setup on my laptop at home (Windows 7 partition, boot partition, and LVM partition, same kernel line in grub too) and it works fine. It seems like it's something with this specific computer here sad

Re: Grub hangs when booting kernel [SOLVED]

Well I managed to fix my problem by using Grub2 (1.97.x) instead of Grub-legacy. Very weird, but at least it's fixed.
