** Description changed: I found this bug after doing a fresh install of Ubuntu 10.04 LTS server (amd64) on a Dell PowerEdge R410, with hardware RAID (SCSI storage controller SAS1068E PCI-Express Fusion-MPT SAS (LSI Logic / Symbios Logic)). Before installing Ubuntu 10.04, this server was booting without a problem with CentOS 5.4 (Linux 2.6.18) - When the installation is over and after the first reboot, I get this error message - "Gave up waiting for root device. + When the installation is over and after the first reboot, I get this error message + "Gave up waiting for root device. ...
