Hello.

About a month ago I installed a security update that had new Kernek 2.6.34.x from 2.6.33.x), this is when the problem occurred for the first time.

After the install my computer would not boot at all, black screen without any visible hard drive activity (I gave it good 30 minutes on black screen, before took actions)... I poped in installation DVD and went in rescue mode to change back the boot option to old kernel (was just a guess where the problem was). After restart computer loaded just file, took a long time for it to start because of SELinux targeted policy relabel is required. Relabeling could take very long time depending on file size. I assumed that the update got messed up somehow and continued working with modified boot option.

Couple of days ago, there was another kernel update. I installed it and same problem as before. This rules out corrupted update theory... Black screen right after 'BIOS' screen before OS gets loaded. I had to rescue system again... Below is copy of my grub.conf file. I am fairly new to LINUX (couple of years of experience), mostly development and basic config... nothing crazy.
