 |
|
Hi there.
This is a completly new setup, on a new computer, so i am sure i've missed out on something. The problem is, i don't what - and i cant figure it out. I need some help debugging this. Can i somehow make the kernel simply not die, or kind log the sequence, or whatever to let me know it's actions and failures.
Thanks.

i recommend to boot a live cd and check your grub setup, are the entries in the grub.conf right ? is grub coming up at all ? cant you be more specific what happens when you try to boot ? good look , cant be that hard ...

Sorry for being unspecific.
Grub is fine, it boots the kernel. I'm on a livecd right now.
I got a tip on adding adding the "panic" flag to grub, which i'll try right after an system update.

you said the kernel boots, so for what are you going to add "panic" useflag for grub ? i dont think grub is responsible after successful kernel loading..

It's not a USE-flags, it's a flag to the kernel, telling it to not reboot if it panics.

Turns out it's not a kernel panic after all.
The computer simply reboots. Any way to log the occurance?

What kind of hardware do you have ?
The rebooting thing can happen if you compile an i686 kernel, and try to run it on an i586 CPU ... |

There, i'm in an Ubuntu enviroment right now, seems to work fine, so it must be my fault.
I'll try getting the .config and copying it to the next Gentoo-installation.
