Description Paul Taylor 2005-07-30 15:40:33 UTC
As discussed in the linked Gentoo Forums thread, attempting to boot a
genkernel-3.3.3 generated kernel (gentoo-sources-2.6.12-r6) with initramfs
support fails with the following error messages:

   .: 8: Can't open /etc/startup.conf
   Kernel panic - not syncing: Attempted to kill init! 

The problem occurs on both my amd64 and x86 (Athlon XP) systems.

Initially, this was thought to be related to enabling genflash, but the problem
persists when gensplash and splash-related boot parameters are removed.

I have not tried rolling back genkernel to an earlier version (3.3.3 is marked
stable.)


Here is an example of a grub entry that generates the error:

title Gentoo Linux (2.6.12-gentoo-r6)
        root (hd0,0)
        kernel /kernel-genkernel-x86-2.6.12-gentoo-r6 root=/dev/ram0
init=/linuxrc real_root=/dev/hda3 video=vesa:ywrap,pmipal,mtrr,1280x1024-32@85
splash=verbose,theme:default CONSOLE=/dev/tty1 quiet
        initrd /initramfs-genkernel-x86-2.6.12-gentoo-r6


And the workaround:

title Gentoo Linux (2.6.12-gentoo-r6)
        root (hd0,0)
        kernel /kernel-genkernel-x86-2.6.12-gentoo-r6 root=/dev/hda3
video=vesa:ywrap,pmipal,mtrr,1280x1024-32@85 


Output from emerge info (for the x86 box):

*sigh*

Be sure to emerge sync before filing bugs... this one is resolved in 3.3.4 and 3.3.5, which should be hitting 
portage shortly, but 3.3.4 has been in for a while.
Comment 2 Henk Poley 2005-07-30 16:18:22 UTC
Hmm, I emerged genkernel this morning (~7hrs ago). What do you call "has been 
in for a while"? 
 
Anyways, thanks for fixing it :-) 
Comment 3 Paul Taylor 2005-07-30 16:24:54 UTC
3.3.4 wasn't on the local (Australian) mirror when I posted the bug, but it
appears to be there now.
