Re: I can't boot "crc error" [Solved]

This issue is currently discussed on #archlinux in IRC.

One possibility to solve this problem is to chroot (or directly boot) into your system with a live cd (or your archlinux install cd) from where you can downgrade the kernel, because it's a bug in the current i686 kernel.

brain0 is already about to fix this in a new package release.

http://wiki.archlinux.org/index.php/Downgrade_packages

Those articles may be helpful though not up to date.
If you have troubles with them, post and I'll post a complete how to.

You can also insert your archlinux installation cd and enter:
arch root=/dev/sda3

whereas /dev/sda3 is your / (root) partition. This will boot your root partition with the installation cd's kernel.

Re: I can't boot "crc error" [Solved]

Thanks again

Solved using this guide:

I just had this problem and fixed it by...

boot with another linux CD (arch install disk will work)

Mount the partition that contains your Arch install.

enter the mounted directory and type

chroot . /bin/bash

then

cd /var/cache/pacman/pkg/

then type

ls kernel26*

Pick a kernel that is older... and

pacman -U kernel26.......

Fixed my system... 

This sort of thing seems to happen a lot... although this is the first time in about 4 kernel updates...

Re: I can't boot "crc error" [Solved]

Harlekin, would you recommend doing an IngnorePkg=kernel26 in pacman.conf for now, since this seems to be happening for everyone upgrading?

Re: I can't boot "crc error" [Solved]

It seems as if only i686 systems are affected by this bug. So if you're running x86_64 arch, you should be fine without worrying.

If you're running i686, adding the kernel to IgnorePkg may be an option until the new kernel package is released / available for your mirror.
As brain0 already updated the kernel package, I'd simply wait with a system upgrade until your mirror is sync'ed.

Re: I can't boot "crc error" [Solved]

First post here, so my question is probably caused by not knowing the history of Arch well enough.

This thread is labeled "solved", but others are still open, so my question is:

- both kernel26-2.6.22.4-2.1 and kernel26-2.6.22.4-2 gives a "crc erro" - maybe not for all users but for quite many - so are we expecting a new updated one, or the above will stay until it will eventually be updated for other reasons?

I've no problem, because I had the install CD and could easily roll back to the kernel26.2.6.22.3-1. I'm not questioning anything (I'm very pleased with Arch which so far is exactly what I searched for), I'm just interested in how these matters usually work regarding Arch.

kernel26 2.6.22.4-2.1 is now in the repos, and solves this problem.

Re: I can't boot "crc error" [Solved]

Hm, browsing the repo packages shows kernel26 2.6.22.4-2.1 to be the current kernel (http://www.archlinux.org/packages/4197/). However if using Pacman there's no ~-2.1 but just the broken (in my system) ~2.2. I've syncronized pacman several times during the day and still it doesn't give any ~2.1 kernel. What am I doing wrong?

The only thing you're doing wrong is being too fast.   Your selected mirror probably hasn't synchronized with the master server yet - just give it a bit of time and it should show up.

Ah, stupid me! I totally forgot about the mirrors. I believe my brain hasn't got synchronized either; to bad there's no master brain to connect to.

Thanks!

Re: I can't boot "crc error" [Solved]

Hello, is this thread still active?

I'm also having the "crc error", only in my case the error is on a Ubuntu distribution, not ArchLinux! I've already tried asking on Ubuntu forums, but got directed here!

I'm wondering if the same solution that was suggested here, will also work on mine, only perhaps changing the commands a little bit? I have Ubuntu 8.10, by the way!

Cheers!
