Linux from scratch cannot boot

zachtib · 05-16-2005, 05:36 PM

I finished my linux from scratch installation, but when I boot to it, I get a call trace followed by

Code:

Code: 08 00 00 00 ba d0 24 c0 00 00 00 00 00 40 fb f7 01 00 00 00
 <0>Kernel panic: Attempted to kill init!
bad: scheduling while atomic!
 [<c03f16c8>]

whats going on, and how to I fix it?

edit: rebooted and got

Code:

ACPI: Subsystem revision 20040326
Unable to handle kernel NULL pointer dereference<1>Unable to handle kernel paging request at virtual address 9a18c045

this seems to be a kernel compilation error,just check kernel config file....

with regards,

You could try disabling ACPI support at boot, when the grub screen appears, hit the 'e' key to edit, highlight the kernel entry line and hit 'e' again, change the kernel entry by appending 'acpi=off'.

For example...

kernel /boot/lfskernel-2.6.8.1 root=/dev/hda1 acpi=off

hit return when done and hit 'b' to boot.

ACPI stands for Advanced Configuration and Power Interface, some M/Boards behave very badly when its enabled, exhibiting all kinds of symptoms such as those you experienced. ACPI controls things like auto power off, battery management for laptops, fans and a whole list of things I have forgotten. My M/Board for instance, is based on the i865PERL chipset and refused to work with an SMP+ACPI enabled 2.6.8.1 kernel without being patched, subsequent kernel relases have worked fine with it.
