Upon reboot I receive the following - can't find my block device type error:

Cannot open root device "sda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)


Few things to look at

1.) What are the IBM drivers used for this card - do they recommend the Megaraid drivers or 3rd party drivers ? 2.) Are you using a modular or monolithic kernel in terms of your drivers for the disk controller and related components 3.) whats in the Debians initrd ? why would an initrd be needed if these devices are supported by the kernel properly - is Debian even using the initrd for the disk drivers and is this a red herring 4.) Check your grub options, make sure they are right, its easy to make a mistake
5.) make sure you have the right filesystem support in your kernel.
