Re: Kernel panic: unable to mount root

make sure you compiled the kernel with the driver(s) needed to access your
hdd, did you see an IDE scan go on during boot?

sample output from a VIA MVP3 based Super Socket 7 board would be:

VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xe000-0xe007, BIOS settings: hda:DMA, hdb:DMA
ide0: VIA Bus-Master (U)DMA Timing Config Success
    ide1: BM-DMA at 0xe008-0xe00f, BIOS settings: hdc:DMA, hdd:DMA
ide1: VIA Bus-Master (U)DMA Timing Config Success
hda: IBM-DJNA-370910, ATA DISK drive
hdb: IBM-DPTA-353750, ATA DISK drive
hdc: CD-ROM CDU4011, ATAPI CDROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: IBM-DJNA-370910, 8693MB w/1966kB Cache, CHS=1108/255/63
hdb: IBM-DPTA-353750, 35772MB w/1961kB Cache, CHS=4560/255/63
hdc: ATAPI 40X CD-ROM drive, 120kB Cache
Uniform CDROM driver Revision: 2.55
hdd: ATAPI 32X CD-ROM drive, 128kB Cache

chekc your kernel config, this is likely the problem.
