    In a case of root=/dev/ram0 real_root=/dev/sda2
    No filesystem could mount root, tried: ext3 ext2...
    Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)
    http://imageplay.net/img/tya22288136/IMG0204A.jpg (real_root - real panic)

    The case of omitting real_root and using just root=/dev/sda2
    VFS: Mounted root (ext2 filesystem) readonly on device 8:2
    http://imageplay.net/img/tya22288134/IMG0203A.jpg - after the last line hangs without panic (alt+sysrq+b helps)

    List of all partitions (before kernel panic string):
    0800 62522712 sda driver: sd
    0801 204800 sda1 00000000-........0
    0802 53928280 sda2 0...............0
    0803 8388608 sda3 0........0
    panic.....
    Pid: 1, comm: swapper/0 Not tainted 3.4.9-gentoo #7

    And in the hope of "Chapter 7", Linux Sea - my case could be some overlooked controller for my SSD Crucial M4 64. I need to clarify SSD is different with HDD in Kernel Setup? Or slightly.. mb AHCI+SATA+RAID is a must chain? As I have an AMD (asrock mb) I couldn't find where is my missed option PIIX (Intel PIIX or AMD analogy).
    RAM and root file system support seem to be not very far from working system:

    - genkernel failed in the same way (VFS). That's why i began my long path make && make_modules
    I've done the kernel without initramfs [*] and 2 partitions in ext2 (/boot ,/ ) in order to lessen the possibility of fail (esp on SSD). I can't fild those two in kernel except for Marvell:
    Code:
    00:11.0 SATA controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 SATA Controller [AHCI mode]
    00:14.1 IDE interface: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 IDE Controller
    03:00.0 SATA controller: Marvell Technology Group Ltd. 88SE9120 SATA 6Gb/s Controller (rev 12)
    I have no HDD only SSD and bootable flash minimal x86_64. Is an "PIIX4 PATA/SATA support" approprietable to me?
    Why bzImage is in arch/x86/boot/bzImage (x86_64 only links to x86). And what i'm doing - recompiling kernel again & again with replaceing with cp.


    Based on Pappy Kernel Seeds. ((Thanks to all you.. to this forum, the art of not being rude to ppl. with creative environment))
