[SOLVED] I screwed up my kernel hooks... I think

I upgraded to the newest kernel and when I rebooted... failure. Here's what did manage to printout when I tried:

Console: switching to colour frame buffer device 128x48

        Type 'reboot' to reboot

Note: klibc contains no 'ls' binary, use 'echo *' instead

If the device '/dev/disk/by-uuid/1720446b-eb15-raf6-94c4-1aa40e959b29' gets created while you are here,
try adding 'rootdelay=10' or higher to the kernel command-line
ramfs$

Reboot gets me the same and exiting results in a kernel panic.

Ok, so what I think happened. With the old kernel I spent a lot of time screwing around trying to make my comp boot faster. One of the things I did was to delete the [ide] and [sata] hooks from my mkinitcpio.conf. At the time I looked up my computer (Compaq Presario F700) and saw that it had a scsi harddrive and thought that I didn't need the other 2 hooks (Does my laptop need them? All this is a guess based on the fact that it all screwed up and that its probably my fault). Looking back, I don't think I even did that tweak right because I don't remember regenerating the kernel and fallback images. Its probably been sitting there just waiting. So when I updated to the new kernel today it did the regenerating and because I screwed with the settings... failure. It can't read my harddrive anymore.

My questions are this: Am I right in what I did wrong? and how do I fix it?

Thanks in advance.

Where did you hear it has a SCSI drive?

http://h10010.www1.hp.com/wwpc/in/en/ho … 48233.html would indicate you have a SATA drive.

Does the fallback kernel work?

I don't remember where I got that faulty info, but I was a fool for trusting it.

The fallback kernel has the same problem. Probably because it was made using the same hooks.

More updates: I found my recovery disk. Booted into it and mounted my HDD. Changed the hooks in mkinitcpio.conf back to the originals. Ran 'mkinitcpio -g /mnt/boot/kernel26.img' trying to rebuild the image based on correct hooks based on the info on the mkinitcpio page of the ArchWiki. Didn't seem to work though, think I need to reread the man page. Anyone know the command(s) I should be running?

Re: [SOLVED] I screwed up my kernel hooks... I think

Solved! Problem is fixed.

I booted from a recovery CD, followed these directions (http://wiki.archlinux.org/index.php/Boo … omplicated) to manually mount root and then rebuilt the kernel image with 'mkinitcpio -g /boot/kernel26.img -k 2.6.30-ARCH'.

And I didn't even need to visit any site other than the ArchWiki, you've gotta love that wiki.:D
