I install archlinux (latest iso from the repository), then I install broadcom-wl and connect to the network to run

pacman -Syu

everything is OK, then I run

pacman -Syu

again, it ask that shall I replace module-init with kmod I type yes, and archlinux says

rc.conf and profile.d/locale.sh conflicts.

I found the -f option will force replace the configuration So I try

pacman -Syuf

After i reboot It shows that

cannot find device /dev/sda7

then a recovery shell is displayed.

I can never boot archlinux again! I check the menu.list from windows xp, found it OK,

# (0) Arch Linux
title  Arch Linux
root   (hd0,6)
kernel /boot/vmlinuz-linux root=/dev/sda7 ro
initrd /boot/initramfs-linux.img

# (1) Arch Linux
title  Arch Linux Fallback
root   (hd0,6)
kernel /boot/vmlinuz-linux root=/dev/sda7 ro
initrd /boot/initramfs-linux-fallback.img

# (2) Windows
title Windows

pacman -Syufwill break your system. You should refer to this news item archlinux.org/news/…;. – jasonwryan Feb 18 '12 at 6:18

This truly is a hard one, but I went through it aswell. Also it is no grub problem!

  1. create an arch live stick and boot it

  2. mount your root partition to /mnt on the live stick

  3. mount your /proc partition to /mnt/proc using mount -t procfs proc /mnt/proc

  4. mount your /sys partition to /mnt/sys using mount -t sysfs sys /mnt/sys

  5. mount your /dev partition to /mnt/dev using mount -t tmpdevfs dev /mnt/dev

  6. mount your /boot partition to /mnt/boot

  7. chroot into /mnt using chroot /mnt

  8. now perform pacman -Syu and watch your kernel being built.

  9. finally type exit and reboot. remove your stick and boot into your now working arch linux

I hope this works for you as well as it did for me :)

this may work. The only problem is I have wireless network connection only, but have no broadcom-wl mod after i upgrade. – jilen Feb 29 '12 at 12:31
