Description of problem: AMD Athlon64 system with SATA disk, one small SCSI disk, and two CD multichangers. Other I/O cards are a 3c90x, a sharedware and an ATI Radeon 9000 series. Generic VIA chipset, only vaguely odd onboard component is a VIA Velocity. At boot nothing is displayed after the grub messages. FC2 installs correctly but it seems that the current FC2 errata kernel also fails on this h/w while the 2.6.6 one is ok.
BIOS problem although why 2.6.6->8 required a BIOS update is anyones guess!
