Hi all,

i just had the idea to make a new ext4 partition (via mkfs.ext4) and copy
(cp) my whole root-dir into that new partition, change the /etc/fstab, add
an entry to the grub.conf and booting into that new partition. My /boot is
on a separate ext3 partition, so this is not a problem. The kernel i use is
gentoo-sources 2.6.28-r1 with ext4-support enabled. However, when i want to
boot into my new system, the system starts, even the uvesafb starts, but
than the booting process stops with a message like "tty starting" and the
system reboots.

I removed all the files in /proc /dev and /sys, so probably this could be
the cause of the problem. Or does anyone have an idea what could be the
problematic factor here? unfortunately i can't provide any logging
information because i can't get to a working shell

Greetings,
Niklas

Don't know if it is related, but for me I had to put rootfstype=ext4
on the kernel commandline. Also make sure you're using
sys-boot/grub-0.97-r9, I know it has ext4 support.

Make sure you have /dev/console and /dev/null in place ... it's needed
*before* /dev is mounted over with tmpfs for udev.

yeah, but my /boot is still ext3 and grub IS actually loading the system, it
even runs uvesafb. or is grub even incompatible with ext4 root-filesystems?
i thought this was entirely handled by the kernel.

hint

I actually have that parameter on the kernel command line. I'll check my
grub version, though, thank you.

I have ext4 root filesystem on 2 machines running gentoo & grub and
it's working fine. Don't give up

Be sure to re-install grub to MBR as well. Just emerging it won't be
good enough.
