kernel won't boot

Oops.  A bad one.  Rebooted about ten minutes ago (in Windows now. . .:-( ) and upon boot the  hooks (udev, etc.) are parsed correctly and those things are loaded, but when the kernel tries to mount the root filesystem, i get something like "could not find root filesystem /dev/sda1 does not exist, trying to create it" then i'm dropped to an emergency shell.  Those messages aren't exact, but the closest that i can remeber.  I could just do a clean instlal, as my home directory is on a seperate partition, but for science's sake, i'd like to see if i can fix this.  any help at all would be great.  thank you.

Re: kernel won't boot

Can you boot with the fallback image?  A probable solution, in either case, would be to boot into the system somehow (fallback image or arch install CD) and then to regenerate mkinitcpio images with mkinitcpio -p kernel26.

Re: kernel won't boot

no fall back doesn't work.  thanks for the fast reply btw.  so i should use a livecd and chroot in and then regenerate mkinitcpio images? sounds good to me.  i'm still a little hairy on the kernel sometimes and i love learning about it ( even through oopsies :-) )
thank you

Re: kernel won't boot

Not to hijack the thread but what exactly is the fallback kernel in arch?  Is this simply the previous kernel?  Also, in arch why is the kernel named 2.6.26-ARCH instead of the the actual full name 2.6.26.5-1?  No big deal.  I was just curious being a former FC user.

Re: kernel won't boot

i had a similar problem after the last pacman -Syu, basicly the bootsplash-initscripts are not compatible with latest udev

maybe it helps

No.

Check mkinitcpio.conf for the HOOKS-section and then check the same section in the fallback-folder. Basically you can strip down the regular kernel to the bare minimum and in the fallback kernel you should keep all HOOKs.
