  This error is caused by multiple reboots which lead to IPMI errors. Consider updating the iDRAC firmware. Re-seat the controller and ends of the cables connected to the controller. What device is installed on the PCIe slot 4? Re-seat all PCIe devices and reboot. Reply to my e-mail with DSET report.
