Bug#455923: Failt to mount the root filesystem of sata hard disc on amd64 kernel

[Paulo Diovani]

i added this source in mine /etc/apt/sources.list:

## Debian Kernel Snapshots
deb http://kernel-archive.buildserver.net/debian-kernel trunk main

and installed the 2.6.24-rc7-amd64 linux version.
it's working all fine now, with the new kernel, until now. hope it stays
this way.

maybe the problem was a bug on the 2.6.22~2.6.23 kernel versions, or just a
compatibility problem with my sata hd. in any case, thanks all for the help.

well, strangely, if i add ahci to /etc/modprobe.d/blacklist the system still
dont boots, and then i need, on busybox, to remove the module from
/etc/modprobe.d/balcklist and load it again. so i can boot.

:(
in resume, my pc almost never boot alone, at first time.

I think i found the problem.
Once on busybox, if i unload the 'ahci' module, then run 'udevtrigger', the
sata hd is recognized and, on 'exit' busybox, the root filesystem is mounted
fine.
So, it seens that all i need to do is to build a new kernel, with the
ata_piix module and without the ahci.

Package: linux-image
Version: 2.6.23-1-amd64

my kernel does not create /dev/sda1 (root) on boot. grub loads from
the same hd and, sometimes, the system works fine, but in most of'em i
fall into busybox and have only /dev/hda (cdrom).
I changed the /dev/name by UUID= at grub and fstab.
I placed some sata modules
(scsi_mod,sd_mod,libata,sata_nv,ahci,ata_piix) at
/etc/initramfs-tools/modules.
Booted with 'noapic' and/or 'acpi=off' options.
...None of it worked.
