I did a complete new installation with the same image as before from
23. Aug 2010, it was an expert installation, but I accepted all
default values, so no custom things were done, apart from this:
Just before the initrd is generated, I added ata-generic to 
/etc/initramfs-tools/modules (on the second console).
That way, the ata-generic got included in the initrd.

When I boot now, the root filesystem still cannot be found.


Some output from the initramfs-shell:

(initramfs) cat /proc/modules
ide_gd_mod 17175 0 - Live 0xc295f000
ide-core 59674 1 ide_gd_mod, Live 0xc2939000
fan 2590 0 - Live 0xc282a000
thermal 9210 0 - Live 0xc290b000
ata_generic 2015 0 - Live 0xc2820000
libata 117275 1 ata_generic, Live 0xc288c000
scsi_mod 102265 1 libata, Live 0xc2863000

(initramfs) cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-2.6.32-5-486 root=/dev/hda1 ro all_generic_ide quiet

As this does not boot, I tried again a new installation, and forced to
add ide_generic to the initrd, and that works! The machine boots fine
with ide_generic.
But as this is an obsolete driver, you may not be interested in info
about this.


Thanks

Holger
