Hi there!
I am migrating my linux laptop from a kernel 2.4.27-2 to a 2.6.12.6
one. Since I compiled the 2.6.12.6 kernel and booted my laptop, I am
receiving the following message when chose the 2.6.12.6 entry in the
grub menu:
mount: mount point dev does not exist
pivot_root: No such file or directory
/sbin/init: 432: cannot open dev/console: No such file
Kernel panic - not syncing: Attempted to kill init!
But when I chose the 2.4.27 entry in the grub meno, my laptop boots ok!
My laptop is running Debian Sarge 3.1a, kernel 2.4.27-2 (that it is
booting ok) and kernel 2.4.6.12.6 (kernel.org kernel). I compiled the
2.6.12.6 kernel with all needed modules (sata disk, ext3 ... including
devfs support), maked a initrd image with the necessary modules to mount
the / partition (sata modules, file system modules...) and changed the
disks names in the /etc/fstab from hda to sda (as it is recognized at
2.6.12.6 kernel bootup process). The laptop model is IBM Thinkpad T43.
That hda to sda looks funny. I didn't know the T43 has a SCSI (which I'm
pretty sure it doesn't).
It may have SATA, which would show up as sda.
yeah, my laptop has SATA disks and it is recognized as a sda disk...
Do you have all of the necessary SATA drivers and sd.o (sd.ko
if modules) present?
I think I do. The SATA controller is recognized at the boot time and
the driver loaded is ata_piix, the boot process messages also shows the
partiotion table.
All modules dependences are in the initrd file (scsi_mod, libata,
sd_mod) and the initrd file has the /dev/console device. The laptop
kernel doesn't have the "sd.ko" module, I think in my case the module sd
is the sd_mod, right?
Any ideia? Anybody knows why it is happen?
Are you sure the initrd was correctly made. That pivot_root seems to
suggest that it wasn't. You're using Debian. When I went from 2.4 to 2.6
I just used aptitude (or apt-get) to get the 2.6 kernel first, and let the
package manager make all the necessary changes for me. I also usually
don't use an initrd and just compile in the drivers for my ide and
filesystems.
I got the sarge official kernel package with all dependences (via
apt-get), installed it and the new kernel has the same problem that the
manualy compiled one has!
Any ideias?
