Details

After running "pacman -Syu" today, I am no longer able to boot using /boot/kernel26.img (I can still boot with kernel26-fallback.img). When booting, it panics after being unable to open "/config". No error messages appeared while running mkinitcpio. When running "zcat /boot/kernel26.img | cpio -tv", cpio gives the error message "cpio: premature end of file", and the list of files appears to be truncated compared to that of kernel26-fallback.img. I used "pacman -U" to reinstall the kernel package to regenerate to initcpio, but it still had the same problem.

I ran "zcat /boot/kernel26.img | cpio -tv >& kernel26-img_contents.txt" and have attached the output file here. Also attached are an excerpt from /var/log/pacman.log which shows what happened during the system upgrade and the mkinitcpio configuration files for each of the two images.
   kernel26-img_contents.txt (4.2 KiB)
   pacman-log_excerpt.txt (5.1 KiB)
   mkinitcpio.conf (2.3 KiB)
   kernel26-fallback.conf (2.3 KiB)
This task depends upon

I removed "autodetect" from the list of hooks in mkinitcpio.conf, and now it generates a bootable initcpio.

your system didn't include the filesystem modules, what filesystems are you using?

also check if your /boot directory wasn't running out of space
Comment by Andrew Munkres (amunkres) - Tuesday, 21 August 2007, 04:30 GMT
Which filesystems: ext2 (on /boot) and ext3 (on /)
Space on /boot: df -h reports 121M available

Confirmed. Read here for more detail and pacman output:

Reading the thread, and noticing the depmod thing - make sure

* You have module-init-tools installed
* You didn't accidentally extract the cpio image over your base utils... I've seen this happen with similar effects - because you're using klibc-based tools like "modprobe" it screws everything up
