Arch Linux

A couple of days ago I updated my system.I haven't updated for quite a while, to be honest.When I updated I couldn't boot.The error was - http://pastebin.com/m7e3da403 .Then I read there was some problem with the current udev and a kernel version lower than 2.6.27.So I updated my kernel to 2.6.32 as well.However, this didn't solved the problem.Then I read through the forum and saw a couple of similar problems.After editing the fstab like this : http://pastebin.com/m48381f91 I did manage to boot successfully.Actually the only thing I did was to remove the 0 '1' tag from the root partition.Another problem appeared - can't access none of my partitions.Whenever i type fdisk -l I get this output http://pastebin.com/m60b8e93b .It's strange because it doesn't detect even my root partition and i have /dev/sd* or /dev/hd* devices in the /dev.Finally I came across information which helped me solve me problem a little.Everytime I boot i have to enter the following commands : undevadm test /block/hda , udevadm test /block/hda1,2,3,etc otherwise I'm unable to use them.I read everything I found on google, however , I only understood it was something of a bug related to udev and nothing more.
