We have an R620 that we recently added an LSI 12 GB SAS 9300-8e card to. The first time the server was booted there was no issue. Every time after that, it gets stuck at "Initializing Firmware Interfaces". I have tried disabling "Collect Hardware Inventory at Boot" and have disabled the Lifecycle Controller entirely. I have also used a bootable SUU to update the firmware. Nothing has helped. The only way I can get the server to boot up is to disable the PCIe slot that it is installed in through the BIOS, which gets the server running, but doesn't allow me to use the SAS card. Unfortunately, this is a production server in a 24/7 facility, but I have been able to take it offline for a couple of hours at night without affecting end users and troubleshoot remotely through the iDRAC. Any thoughts on this would be greatly appreciated.
