Hi, I need some help with section 8.3 of the lfs book.
--- Problem I am trying to compile the 2.6.16.3 kernel for use with a Dell CERC ATA100/4ch raid controller. I am not using an initrd image. Can someone tell me which drivers I must include? 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) -- Kernel Config I am including the following drivers in my config: SCSI disk support - BLK_DEV_SD LSI Logic RAID Device Drivers - MEGARAID_NEWGEN LSI Logic Management Module - MEGARAID_MM LSI Logic MegaRAID Driver - MEGARAID_MAILBOX LSI Logic Legacy MegaRAID driver - MEGARAID_LEGACY -- Comments / further info I know the drives are good because I can boot using a 2.6.8 kernel from a (Debian) installer using an initrd image. lspci output when booted in 2.6.8 kernel: 0000:00:00.0 Host bridge: ServerWorks GCNB-LE Host Bridge (rev 32) 0000:00:00.1 Host bridge: ServerWorks GCNB-LE Host Bridge 0000:00:02.0 Ethernet controller: Intel Corp. 82540EM Gigabit Ethernet Controller (rev 02) 0000:00:03.0 Ethernet controller: Intel Corp. 82557/8/9 [Ethernet Pro 100] (rev 0d) 0000:00:07.0 I2O: American Megatrends Inc.
