Hi there!
I have a IBM ThinkPad t43 running Fedora Core Linux 4 and kernel 2.6.12-1.146_FC4. I recompiled the kernel (2.6.13.4 - kernel.org) and I am geting the following message when the computer boots:
Creating root device mkrootdev: label / not found Mounting root filesystem mount: error 2 mouting ext3 Switchimg to new root ERROR opening /dev/console!!!!: 2 switchroot: mount failed: 22 Kernel Panic - not syncing to kill init!
I added the fdisk command to the initrd file and the init script executes it every boot to check if the kernel was recognizing the SATA disk. All partitions are listed in the boot process and the disk is recognized without problems, but the kernel still not able to mount the root partition:
scsi0: ata_piix ... ... Attached scsi disk sda at scsi0, channel 0, id 0, lun 0
Disk /dev/sda: 60.0 GB, 60011642880 bytes 255 heads, 63 sectors/track, 7296 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 1913 15361888+ 7 HPFS/NTFS Partition 1 does not end on cylinder boundary. /dev/sda2 6778 7296 4165560 12 Compaq diagnostics Partition 2 does not end on cylinder boundary. /dev/sda3 1914 1929 128520 83 Linux /dev/sda4 1930 6777 38941560 5 Extended /dev/sda5 1930 2843 7341673+ 8e Linux LVM /dev/sda6 2844 3235 3148708+ 83 Linux /dev/sda7 3236 6777 28451083+ b W95 FAT32 Partition table entries are not in disk order
I also checked the initrd file and all seems ok. Thinks I made:
- compiled the kernel with ext3 modular support; - compiled the kernel with ext3 built-in support; - checked the modules loaded in the initrd; - rebuilded and customized the initrd; - checked if the SATA controller is recognized at boot time; - tested fstab with and without "LABEL" partition name.
Any idea?
