Several startup kernel errors

Annie25 · 06-09-2007, 06:26 PM

I'm using ubuntu 7.04, and I have downloaded and compiled kernel 2.6.21, and created an initrd file, but when I try to boot from that kernel, the kernel prints this:

[15.001742]PCI: BIOS Bug: MFCG area at f0000000 is not E820-reserved
[15.001778]PCI: Not using MMCONFIG
mount: unknow filesystem type 'devfs'
umount: devfs: not mounted
/scripts/ext3-add-journal.sh:arith:syntax error:"0x"
mount:unknow filesystem 'devfs'
/sbin/init:426:arith:syntax error: "0x"
[16.590091]Kernel panic - not syncing: Attempted to kill init!

And them it freezes, what's my problem?

The kernel is unable to mount the "/" partition!

Maybe you have not compiled devfs in the kernel, or maybe your initrd file is not correct... maybe your kernel even have the option devfs since it have been obsoleted, have a look on kernel Changelog:

Code:

DevFS has been obsoleted in favour of udev
(http://www.kernel.org/pub/linux/utils/kernel/hotplug/)

Anyway, try to specify your partition type in /dev/fstab and boot again!

But you should stop using devfs!

[]'s, FMC!

The initrd.img need to be created by initramfs but initrd. Is yours?
