A Dell T420 with at a small office crashed on restart. The Dell Red Screen Of Death (RSOD) was happening at boot.
This single processor unit with a H310 controller had internal non hot swappable IDE drives. Pretty standard setup for light duty use. On reboot examining the RAID controller screen showed a drive in rebuilding state. This situation caused the RSOD.
Simply waiting for the drive to rebuild (about 6 hours) and then restarting the system fixed the RSOD. Unknown if a BIOS or other firmware update will correct this problem.
