Matt, Thanks for your reply.
My initial responses are: 1. this computer was manufactured by Dell not IBM. Not sure if I am misunderstanding something. 2. Monolithic kernel - as per the lfs suggestions. There is a chicken-egg problem if I use a modular driver for the raid 3. The debian installer always creates an initrd. LFS book suggests not using one. I need to look in to how I can check what is in the initrd image. 4. Grub options are pretty straight forward in this case. But I will check again 5. Filesystem support is correct: Ext2, Ext3 PT -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Matt Darcy Sent: Thursday, April 13, 2006 9:33 AM To: LFS Support List Subject: Re: kernel panic - Dell CERC ATA100/4ch raid controller > > 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.
