I installed Gnome etc. Then I came to replace the 40GB drive which contained backups with a DVD-ROM drive. This was my first reboot of the system since install. I shut it down and replaced the hard disk with the DVD-ROM and booted up. At the boot loader I chose the default option and it booted as far as the following lines and then halted with a complete lock up. acd0: DVDROM at ata1-master UDMA33 acd1: DVDR at ata1-slave UDMA33 A verbose boot halted with the following two lines: GEOM: Configure ad1s1c, start 0 length 200047002624 end 200047002623 GEOM: Configure ad1s1d, start 0 length 200047002624 end 200047002623 I origionally thought it was a problem with my SiL 3112A SATA chipset (known to be problematic) so I disabled that with a motherboard jumper and it made no difference. Then I considered a problem with one of my devices so I unplugged everything except the 60GB disk which contains the FreeBSD operating system itself. I also tried several combinations of different devices and the system always hangs right after the detection of devices or after the GEOM: Configure in verbose mode. I've tried booting in safe mode, non-acpi and verbose modes and have exactly the same problem in all three. One odd thing I have noticed is that in the boot prompt if I do lsdev it only shows the DVD drives if they have a disk in - I assume this is correct? Any suggestions on what I can try next will be greatly appreciated. Any more information you need I will try and provide.
