I'm trying to do an unattended install of FreeBSD 5.2.1.  If I don't                                                        
include the 'shutdown' command at the end of the install.cfg file, the                                                      
install works fine, but I have to manually reboot the machine after the                                                     
install, which is no good for an unattended install.                                                                        
                                                                                                                            
If I do include 'shutdown', then it appears that the disk does not unmount                                                  
properly before the reboot.  The console displays "syncing                                                                  
disks, buffers remaining".  Normally I would expect a few                                                                   
numbers to be printed, followed by a reboot a second later. This what                                                       
happens if the reboot is performed manually from the sysinstall menu.                                                       
                                                                                                                            
But when the reboot is performed automatically, after "syncing disks"  it                                                   
says: "WARNING - WRITE_DMA interrupt was seen but timeout fired LBA" and                                                    
then prints the same number (e.g. 161) over and over again for several                                                      
lines.  After about 5 seconds the system reboots, but the new installation                                                  
has errors on the filesystem and requires me to manually run fsck. This is                                                  
no good for an unattended installation.
