A client was attempting to install ESXi 5.0 U2 on a DL380p Gen8. The server would not boot into Intelligent Provisioning and when they tried to manually install ESXi it would PSOD. Contained in the message would be “"Can't detect the last level cache, PCPU0: 4096/bootstrap PCPU0: SISISISISISXXXXXXXXX”
Cause and Resolution : disconnect non hp mouse, keyboard which were plugged directly into the server since there was no ILO or KVM. Disconnecting these resolved the issue.
