 Follow up:
 
 Managed to get it to complete install again, and boot, twice. First time it booted up with
 a "read command timeout" error then a loop of reseting devices, write error, resetting
 devices, etc, after the UDMA startup sequence. After this the filesystem got ruined and it
 would not boot again. Second time though I managed to boot and login, it failed to start
 up the DMA mode on startup so didn't go all haywire. Placed
 
 /sbin/sysctl -w hw.atamodes="pio,dma"
 
 into /etc/rc.conf which has allowed me to boot every time successfully and the DMA related
 error messages have gone. However, this obviously comes at the cost of abysmal hard drive
 performance.
 
 Hope this helps to narrow down where the problem lies.
 
 Mark
