Grub configuration after new kernel instalation using pacman

Hi there,

i have compiled kernel from source using makepkg and pacman as descripted at http://wiki.archlinux.org/index.php/Ker … rom_Source but i'm having some troubles to boot this new kenel. I get the following message:

RAMDISK: Couldn't find valid RAM disk image starting at 0.
Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floopy.
VFS: Insert root floppy and press ENTER.

The grub lines i have added for this kernel boot are:

title     xpto
root    (hd0,2)
kernel /boot/vmlinuz26-my root=/dev/dev3 ro
initrd   /boot/kconfig26-my

Any ideas?

Thanks in advance.

I think that the problem is that the old kernel recognizes my disk as /dev/sda and the ramfs as /dev/hda. :s

Re: Grub configuration after new kernel instalation using pacman

The problem is with your initrd line.
1) if you compiled all the modules needed to mount / (ie. PATA/SATA/usb, and filesystem modules), you don't need initrd at all.
2) if you're using initrd generated by mkinitcpio, the file will definitely something else, not named kconfig26-my. That file is most likely a text file containing you kernel config.
