Hi,

ich wollte mal wieder einen neueren kernel
:mit genkernel gebaut und in grub.conf eingetragen mit root=UUID=*** (auch fstab)

aber ich erhalte beim booten folgenden fehler

Code:

>> Determining root device
>> Detected real_root=/dev/sdb2
>> Mounting /dev/sdb2 as root
>> Using mount -t btrfs -o ro
mount: mounting /dev/sdb2 on /newroot failed: No such device
!! could not mount specified ROOT, try again
!! could not find the root block device in .


ich glaube ich habe falsche Konfiguration für
Code:

00:1f.2 SATA controller: Intel Corporation 7 Series Chipset Family 6-port SATA Controller [AHCI mode] (rev 04)


mit älteren kernel(conf) klappt es ...

lspci -k zeigt dir, welches kernel modul in Gebrauch, bzw. benötigt ist:
Code:
00:1f.2 SATA controller: Intel Corporation 5 Series/3400 Series Chipset 6 port SATA AHCI Controller (rev 05)
        Subsystem: Dell Device 040a
        Kernel driver in use: ahci
Ich brauche also nur AHCI im kernel. Für Serie 7 dürfte das auch AHCI sein.
