Kernel26-2.6.25 kernel panic

This morning I ran pacman to upgrade the system. It upgraded my current kernel (2,6.24) and installed the new one. I then rebooted to make sure everything worked then, and of course, it didn't. I had a kernel panic, so then after much reading and asking questions, I am finally able to chroot into the drive from the Arch CD.

I then proceeded to downgrade back to the old 2.6.24 kernel, by using:

pacman -d -U /var/cache/pacman/pkg/kernel26-2.6.24.4-1-i686.pkg.tar.gz

With this then, I am able to boot the system, until it loads the modules / daemons, and the system halts. Here is a picture:

I don't know what to do from here, and I am completely stumped. If anyone could give me some pointers or suggestions, I would be much obliged.

Thanks for reading,
Dr Small

This is a complete shot in the dark, but you could
cat /var/log/pacman.log
and see what other packages got installed and downgrade those as well.

Probable that mkinitcpio was upgraded and causes havoc when you downgrade....

Re: Kernel26-2.6.25 kernel panic

I thought you might be right, but I downgraded it too. Still no go. Even when downgrading to the old kernel, I am still getting the same message that I got back on the 2.6.25 kernel:

So, no matter how much I do, I am unable to boot the system.

Gain access to the files on the disk and edit /etc/rc.sysinit, add set -x at the top and set +x at the bottom to turn on debugging and see where it's halting.

I need real, proper pen and paper for this.

That may have been what I needed to do for the first post, but now I can't even get the kernel too boot. See my latest post please.

Re: Kernel26-2.6.25 kernel panic

Go through the checklists here: http://bugs.archlinux.org/task/10534

Basically:

* Boot with fallback to see if it's a module problem
* Ensure menu.lst is pointing to the right vmlinuz and img in the right location
* Run mkinitcpio -vp kernel26 to look out for problems with generating the image itself
