[gentoo-user] strange /init kernel-2.6.12-gentoo-r5 boot problems

[gentoo-user] strange /init kernel-2.6.12-gentoo-r5 boot problems

[Iain Buchanan]

I just compiled kernel-2.6.12-gentoo-r5 almost exactly the same way I've
compiled every other kernel, but this one won't boot!

I used genkernel as so:
sudo genkernel --no-menuconfig --save-config --no-bootsplash --gensplash
--gensplash=emergence --install
--kernel-config=/home/iain/configs/2.6.12-gr5-2005-07-14 --makeopts=-j3
--mountboot --bootloader=grub all

which is the same as I used for 2.6.12-gentoo and 2.6.11-gentoo-r11
(etc) and they worked fine.

The only difference is I removed --udev from the genkernel options
because genkernel told me its specified by default.


The kernel and initrd files are named differently:
kernel-genkernel-x86-2.6.12-gentoo-r5
initramfs-genkernel-x86-2.6.12-gentoo-r5

as opposed to
kernel-2.6.11-gentoo-r11
initrd-2.6.11-gentoo-r11

Grub loads the initrd ok, but somewhere in the boot process, this
happens (with lots more /init lines where I've placed 'etc'):

...
ACPI wakeup devices:
 LID PBTN PCIO USB1 USB2 USB4 USB3 MODM PCIE
ACPI: (supports S0 S1 S3 S4 S4bios S5)
Freeing unused kernel memory: 228k freed

all ok up to here, but then:

/init: 41: In: not found
/init: 45: cat: not found
/init: 150: sed: not found

etc!

etc!

/init: 187: mkdir: not found
>> Determining root device...
!! The root block device is unspecified or not detected.
  Please specify a device to boot, or "shell" for a shell...
boot() :: 

(this is typed from a photo, so E&OE !!)

At this stage, I can type shell, but I don't get any commands.  When I
try to use tab completion, I see some strange directory names (sorry
can't remember exactly).

I thought maybe for some reason I didn't have the right filesystem
modules compiled in, but they're certainly there:

CONFIG_EXT3_FS=y
and so on, but anyway, I haven't changed this from 2.6.11.

So, any ideas on what's going on? Something udev related?  google only
returned the usual "init not found", MARC showed nothing and I can't
connect to gmane, anyone know whats going on there?

Many TIA!

What busybox config? `equery files busybox` doesn't show any config
files for busybox.  I found the previous thread here
http://marc.theaimsgroup.com/?l=gentoo-user&m=112127857419654&w=2 and
Zac suggested some different options:

> splash=verbose gentoo=nodevfs udev devfs=nomount
> initrd /initramfs-genkernel-x86-2.6.12-gentoo-r4n

but that didn't help either.

And why do I need to do a `busybox --install` ?? shouldn't this come up
in some emerge warning or be done by genkernel or something? I monitor
all the output from emerge with enotice, but I didn't see anything about
busybox...

So it still uses the initramfs even though you didn't specify root=/dev/ram0?  Richard said something about that (I wasn't aware of this behavior).  Apparently you need to remove the initrd parameter in order to disable it.

Genkernel builds busybox with the config file in /usr/share/genkernel/$arch/busy-config.  Of course, it will only build busybox if it doesn't find a suitable binary in your bincache (specified in /etc/genkernel.conf).

You don't do busybox --install, that happens automatically in the init script.  It seems that the genkernel devs may have overlooked this minor detail.  It's easy to forget about it after you have a working busybox in your bincache.

[Chee Ong Loh]

solution are simple.
there is a new version of genkernel in portage.

try:
emerge --sync and emerge genkernel
and finally rebuild the entire kernel and that should solve.
At least I've solve mine.

good luckzzzzzz
