I just tried to upgrade a FC2 machine to FC3. Install went fine, but after a reboot - this is all I get: ACPI: BIOS age (2000) fails cutoff (2001), acpi=force is required to enable ACPI audit....bunch of numbers... initialized hda: No disk in drive Red Hat nash version 4.1.18 starting mount: error 6 mounting reiserfs mount: error 2 mounting none switchroot: mount failed: 22 umount /initrd/dev failed: 2 kernel panic..... This happens if I try to launch with either the SMP kernel, or the single processor kernel. The machine is an older dual processor pc, with scsi disk drives - two of them for linux, 1 still has W2K on it. Could the fact that its trying to do something with hda instead of sda have something to do with this? Does that acpi stuff have anything to do with it? I tried adding the force option to the kernel parameters, but it didn't change anything. The only similar reference I can find is http://www.redhat.com/archives/fedora-devel-list/2004-November/msg01096.html which seems to indicate that it is a kernel problem. Any help would be appreciated... Thanks, Dan
