grub reboot loop

Hello to you all

I just installed the latest gentoo linux and everything went fine up to the point when I wanted to load my new system.
The computer starts and the grub screen appears, but instead of loading the kernel grub simply reboots the system... again and again... and I just cant't get into my system..

config:
amd k6/2 400
128mb ram
boot-partition: hda5
root-partition: hda2

grub-entry:
root (hd0,4)
kernel /boot/bzImage root=/dev/hda2

any suggestions?

björn

are you sure you change the prosessor type during buildign your own kernel ??because thats what took my ages to find that I forgot to do it and ended up with the same problem my k6-2 333 rebootign after you hit boot in grub

Is that *all* you have in your config file?

Perhaps try changing it to:

Code: Select all

default 0
title=My Gentoo Default
root (hd0,4) 
kernel /boot/bzImage root=/dev/hda2

Also, does the screen load to the point where you can hit the 'c' button on you keyboard and manually boot if using the grub command line?

By the way, you might also want to put a 'ro' on the end of you kernel line, that way you will mount the root filesystem read-only until the gentoo init scripts remount it as rw.

no no,

the config-file itself does look quite like you describe it...
and yes, grub does load up to the point where I can edit the boot commands and so on.....

greets

Haven't you by chance forgot to mount /boot before copying bzImage?

Hello,

Yes, I definitely mounted my /boot partition. I strictly followed the instructions in the install-guide (including mounting the partitions) and even rechecked bzImage existed in /boot....
maybe I really forgot to enble support for my amd processor when compiling the kernel, like one of you said before....

OK, maybe I'm still too much a newbie to use gentoo, but now that it has happened... what can I do ......?

many thanks for your support

bott from the CD then get into the chroot enviroment and recompile the kernel remembering to set it up for K6-2
copy it to the /boot partition and give it a try

nice weekend

I just recompiled the kernel with support for my K6/2 and I just wanted to let you know everything works fine now...

thanks a lot!!

I had the exact same problem, had to reboot from the cd and recompile after my P200 refused to boot.

Perhaps it would be a good idea to mention selecting your processor type in the installation docs? Not everyone are kernel-compilation wizards, and it's easy to overlook since there are quite a few settings in there.

Just my two euro-cents...
