I have a Tyan S2882 motherboard with a dual core opteron 265 and 2gb of ram. After doing the install and reboot, it would hit grub, then black screen and hang.
instaling in uniprocessor mode hung the system almost immediately during install
installing with apic=off seems to have done the trick with letting the system boot as it is now up and running, but this should not be needed.
The bios on this system is 3.07
tried with both onboard adaptec u320 scsi and the megaraid u320-1 scsi controller.
