    I have been using two hard drives, an old IDE mounted at / and a brand new
    SCSI mounted on /home. A few days ago the IDE drive died. Fortunately, I had
    just copied all the data over to the SCSI drive (/dev/sda1). But when I try
    to boot off the SCSI drive, I get the following messags:

    Freeing unused kernel memory: 152k freed
    NET: Registered protocol family 1
    Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
    ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
    NFORCE2: IDE controller at PCI slot 0000:00:09.0
    NFORCE2: chipset revision 162
    NFORCE2: not 100% native mode: will probe irqs later
    NFORCE2: 0000:00:09.0 (rev a2) UDMA133 controller
            ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:DMA
            ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA
    ide1 at 0x170-0x177,0x376 on irq 15
    pivot_root: No such file or directory
    /sbin/init: 432: cannot open dev/console: No such file
    Kernel panic - not syncing: Attempted to kill init!

    Here are the commands I'm using in GRUB to boot:

    root (hd0,0) <--- this is the scsi disk
    kernel /vmlinuz root=/dev/sda1 ro
    initrd /initrd.img

    I tried building a new initrd (mkinitrd) with 'scsi_mod', 'sd_mod' and
    'sr_mod' added to /etc/mkinitrd/modules, but no improvement. I then built an
    initrd with nearly all the modules from `lsmod` (except a few I was sure
    weren't needed, like soundcore) added to /etc/mkinitrd/modules. I got a few
    more messages when I tried to boot ("USB Mass Storage support
    registered"), but had the exact same error.

    I am using Debian 3.1.
    /sbin/init exists on both /dev/sda1 and the initrd.
    So does /dev/console.
    I DID specify the correct kernel version when building the initrd.
    If possible, I would like a solution short of recompiling the kernel.
