Cyclic reboot after RHEV3 hypervisor instalation

Hi,

After initial installation of rhevh-6.2-20111108.0.iso on a IBM x3550M2, 2 x 146, 32 Gb Ram the machine reboots as it should. - I removed instalation DVD, but the machine cant boot from HDD, and reboots immediately when it comes to HDD. After that it reboots cyclic. I tried installation several times with same result. Also tried to delete raid an install on single disk, same result.

I have made at Support Case (00567500) but tickets on Beta versions are handled as priority 4, and support is slow. - First guess from them was to check the bios of the server and make sure that UEFI mode is set to legacy boot mode, and it was set. I have several RHEV 2.2 running on same HW.

So i'm totally stuck'ed in my test. 
 

Has anyone else seen this problem or similar.
