I recently bought a new motherboard and processor, replacing a MSI 790FX-GD70/ Phenom955 with an Asus sabertooth 990FX/ Bulldozer 8150, all AMD chips, and had to reinstall the linux operation systems Kororaa16x64, Fedora16x64 and Ubuntu11.10x64. Windows was recovered from a system backup. I keep the o.s.'s on two fake raid 0 configs consisting of two ssd's and two hdd's created with the onboard raid controller.
Kororaa and Fedora installed flawlessly, but Ubuntu12.04 beta gave problems during installation of the bootloader. It insisted on putting the bootloader on sda where I specified /dev/mapper/pdc_fgddehjig. Sda happens to be a disk in the raid array, so I was not surprised the system declared it a fatal error.So I decided to not install the ubuntu grub2 bootloader, and to use the grub2 bootloader from Kororaa instead.
Ubuntu12.04 then starts but half way it starts spitting errors and warnings:
gave up waiting for root device
common problems:
-Boot args (cat /proc/cmdline)
-Check root delay= (did the system wait long enough?)
-Check root= (did the system wait for the right device?)
-Missing modules (cat /proc/modules; ls /dev)
ALERT: /dev/dm-7 does not exist Drop into shell
BusyBox .....
(initramfs)
DMraid module is present and if I give the command:
dmraid -ay
all raid partitons are being shown and then it says it can go any further because a non existing raid partition is not there.
First I thought it to be a beta bug, but when I installed 11,10 again I got exactly the same problems.
Now I suspect Ubuntu has a problem with the motherboard chipset of the AMD 990FX.
Can anyone provide me with a sound solution?
