You stated that you are using the Lite version but this version that is Free does not have the cluster feature. The screen shot is showing issues with the IRQ management can you go into the BIO of the motherboard and turn off all power management features then boot again.
I reinstalled open-e, got trial key and put it in DSS.
next i reset bios in HP and disabled all power saving options.
but without luck - the same kernel panic.
next i disabled all cpu features - such as virtualization, DEP, etc. - no luck.
If you interested in logs i can send them to you.
PS: this server ran windows and linux virtual machies with windows 2008 r2 hyper-v without any issues more than 3 years. only hdd and FC adapter were added.
But since i have 3 identiacl FC cards (bios show them as FC1242, DSS as HPAE312A) and tested in various combinations with desctop and server hardware i think this issue related to FC cards..
