I don't know if there is a "debug" mode for the boot loader, but if the problem is happening at random then I would want to investigate hardware failures/malfunctions. At any rate, no fully operational machine should need "several ctrl+alt+delete reboots" for it to start working. Perhaps the problem happens when the BIOS is attempting to probe drive controllers? Have you tried to stress-test the system by doing a "make buildworld"? SC
