roll back kernel version

For the first time I had kernel panic in Arch on old pc that seems to have some hardware issues; I could login on the fallback kernel - recovery mode, but then network wasn't working.

Found this info on kernel panic:

Roll back to previous kernel version

If you keep your downloaded pacman packages, you now can easily roll back. If you didn't keep them, you have to find a way to get a previous kernel version on your system now.

Let's suppose you kept the previous versions. We will now install the last working one.

First you need to get the kernel details.

# cd /var/cache/pacman/pkg
# find kernel*

Now use the kernel details in the command below. Link

# pacman -U /var/cache/pacman/pkg/kernel26-2.6.23.xx-x.pkg.tar.gz
