Hi All, I am trying to boot up 2.6.20-15 Kernel ( Ubuntu Kernel) using my custom initramfs. But I am getting Kernel Panic when I boot using my Init script. I am mentioning my init script below. I have followed the FC7 init script, I really don't know many things which are being used in that.
In this Init script everything goes fie till I execute setuproot, while running setuproot it complains; setuproot: moving /dev failed: No such file or directory no fstab.sys, mounting internal defaults setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory And it gives Kernel Panic after executing switch_root, I am not sure why switch_root is not executing the /sbin/init, is it due to it couldn't find it? 2 Kernel Panic message: [ 47.972305] kjournald starting. Commit interval 5 seconds [ 48.037871] EXT3-fs: mounted filesystem with ordered data mode. [ 48.110173] Kernel panic - not syncing: Attempted to kill init! I really don't know its a problem of busybox or in my Init script. #!/bin/nash mount -t proc /proc /proc setquiet echo Mounting proc filesystem echo Mounting sysfs filesystem mount -t sysfs /sys /sys echo Creating /dev mount -o mode=0755 -t tmpfs /dev /dev mkdir /dev/pts mount -t devpts -o gid=5,mode=620 /dev/pts /dev/pts mkdir /dev/shm mkdir /dev/mapper echo Creating initial device nodes mknod /dev/null c 1 3 mknod /dev/zero c 1 5 mknod /dev/systty c 4 0 mknod /dev/tty c 5 0 mknod /dev/console c 5 12 mknod /dev/ptmx c 5 2 mknod /dev/rtc c 10 135 mknod /dev/tty0 c 4 0 mknod /dev/tty1 c 4 1 mknod /dev/tty2 c 4 2 mknod /dev/tty3 c 4 3 mknod /dev/tty4 c 4 4 mknod /dev/tty5 c 4 5 mknod /dev/tty6 c 4 6 mknod /dev/tty7 c 4 7 mknod /dev/tty8 c 4 8 mknod /dev/tty9 c 4 9 mknod /dev/tty10 c 4 10 mknod /dev/tty11 c 4 11 mknod /dev/tty12 c 4 122 mknod /dev/ttyS0 c 4 64 mknod /dev/ttyS1 c 4 65 mknod /dev/ttyS2 c 4 66 mknod /dev/ttyS3 c 4 67 echo Creating block device nodes. mkblkdevs echo "Loading usbcore.ko module" insmod /lib/usbcore.ko echo "Loading uhci-hcd.ko module" insmod /lib/uhci-hcd.ko echo "Loading ohci-hcd.ko module" insmod /lib/ohci-hcd.ko echo "Loading ehci-hcd.ko module" insmod /lib/ehci-hcd.ko mount -t usbfs /proc/bus/usb /proc/bus/usb echo "Loading mbcache.ko module" insmod /lib/mbcache.ko echo "Loading jbd.ko mo8dule" insmod /lib/jbd.ko echo "Loading ext3.ko module" insmod /lib/ext3.ko echo "Loading scsi_mod.ko module" insmod /lib/scsi_mod.ko echo "Loading sd_mod.ko module" insmod /lib/sd_mod.ko echo "Loading sg.ko module" insmod /lib/sg.ko echo "Loading libata.ko module" insmod /lib/libata.ko echo "Loading ata_generic.ko module" insmod /lib/ata_generic.ko echo "Loading ata_piix.ko module" insmod /lib/ata_piix.ko echo Waiting for driver initialization. stabilized --hash --interval 250 /proc/scsi/scsi insmod /l8ib/scsi_wait_scan.ko rmmod scsi_wait_scan mkblkdevs echo Creating root device. mkrootdev -t ext3 -o defaults,ro sda2 echo Mounting root filesystem. mount -o defaults,ro -t ext3 /dev/sda2 / echo Setting up other filesystems. setuproot echo Switching to new root and running init. exec switch_root / .ext3 /sbin/init echo Booting has failed. sleep -1 Thanks Rajeev Bansal. ******************************************************************************** This email message (including any attachments) is for the sole use of the intended recipient(s) and may contain confidential, proprietary and privileged information.
