I spent whole weekend to install 0710 Beta 3 from the scratch but without luck. There is a very strange situation. After testing BIOS drivers the installator display warning about problem with xfs_freeze(), XFS file system and GRUB. And then the screen is refreshed, cleaned a I can see only the cursor in the left top corner. I waited about 5 hours but the system was in the same stage - blinking cursor in the left top corner.
Once I pressed Ctrl+Alt+Del. After that the installation is finished but it was uncompleted - software modules for DVD was not installed and my network interfaces were eth1 and eth2 instead of eth0 and eth1. The situation seems mystic for because a few days ago I installed on the same box LMCE with the same DVD. So, I don't have any idea why the installation cannot finish properly in that case.
Any suggestions will be very appreciated!
