    Question Help & lead me to the end. VFS: readonly/fs couldn't mount.

    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 (befor kernel panic string):
    0800 62522712 sda driver: sd
    0801 204800 sda1 00000000-........0
    0802 53928280 sda2 0...............0
    0803 8388608 sda3 0........0
    panic.....

    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 save 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))

    Why make life difficult by forcing a SSD not a normal hard disk? As far as the kernel is concrened a SSD is just another block device same as a hard disk. At least that is how I installed mine and I have never had any hang up.
