I had Fedora 17 on my development desktop. It was crashing on constant basis (like someone pull out power cord, yeah that bad

So today I reformat disk and install Fedora 18 KDE from live CD (this time I used btrfs, no lvm anymore).
It was bad. They screw up Anacoda. It failed to find HD while USB drive was connected, only root account created, no network setting asked.
But it was fast (5-6 minutes fast), I spend 20 minutes to install updates.
Hopefully Anaconda on DVD is better.
