[SOLVED] New motherboard yields PCI error Unkown header type 7f

I installed a new motherboard (GA-G41M-Combo) with all the same old hard disks, and stuff. I have two harddisks, sda1 is the boot partition, sdb2 is the encrypted root. On booting I get this error:
http://imgur.com/f5CY3ZN
pci 0000:04:01.1: unknown header type 7f, ignoring device
pci 0000:04:01.0: BAR 0: error updating (0x00d001 != 0xffffffff)
If I boot a live CD, I can unlock the volume, all hard disks are visible and mountable, and the /dev/disk/by-id/... is correct as well.

I have no idea why I'm getting this error, Google gives tons of hits for this error message, I found no helpful information for my situation.
Please help me.

Did you try booting the fallback image?

Yes, I did. There was the same result.

I experimented a little and swapped the SATA connections around. Now the error messages disappeared and the fallback kernel does find the cryptroot! Hooray! But the normal kernel is still unable to find it, althought the error messages disappeared. How do I proceed now?

Run mkinitcpio to regenerate the initramfs.

Thank you, this was the solution. A simple pacman -Syu did the trick. Just for the record, why did I need to regenerate the image?
I mark this as solved.

It looks like you needed different modules for the new hardware.

By default, the mkinitcpio script generates two images after kernel installation or upgrades: /boot/initramfs-linux.img and /boot/initramfs-linux-fallback.img. The fallback image utilizes the same configuration file as the default image, except the autodetect hook is skipped during creation, thus including a full range of modules. The autodetect hook detects required modules and tailors the image for specific hardware, shrinking the initramfs.

I see, thanks for the clarification. I actually didn't know that the normal image is static this way.
