[gentoo-user] grub2 boots only older kernel

[gentoo-user] grub2 boots only older kernel

[James]

Hello,

> grub 2 trouble?
I have 6 different kernels. that show up in /boot and in the grub2 boot menu
of choices.

The lastest version that works is 3.13.6

I cannot get any since then to boot the (FX8350) gentoo system. Very weird.
I even copied of the .config file from 3.13.6 to 3.14.4, answered the 
questions and issued:


make && make modules_install
cp arch/x86_64/boot/bzImage /boot/kernel-3.14.4-gentoo
cp System.map /boot/System.map-3.14.4-gentoo
cp .config /boot/config-3.14.4-gentoo
grub2-mkconfig -o /boot/grub/grub.cfg

/etc/default/grub   has:

GRUB_DEFAULT=kernel-3.14.4-gentoo
GRUB_HIDDEN_TIMEOUT=3
GRUB_TIMEOUT=10
GRUB_GFXMODE=1024x768
GRUB_DISABLE_RECOVERY=true


I need ideas as where to look, what to fix  to get a newer kernel
booting from grub2.  Not any changes since 3.13 series was first used:
(3.13.1) Note this problem started with kernel 3.13.7-gentoo and has
persisted through 3.14.4.  I have even diff the .config files [1]


stumped needing a nudge,
James

This looks fine.

For anyone to give you a useful answer, we would need more detailed
information about your specific issue - for example:

- - how far through the boot process does the "broken" kernel get?
- - Are there any error messages or stack traces?
- - Is there any display at all?
- - What is the kernel cmdline used to boot the kernel?
- - Do you use an initramfs?

As for the kernel diff below, there are obviously a few options changed
between the kernels, but without more information about your hardware and an
idea of what is actually happening, it's difficult to tell if any are the
cause of your issue.

It never tries to boot. Grub just sits there  withe phrase (did not copy 
it down) where it says what version it will boot on the screen
and it does nothing (locked up?) I have to <cntl><alt><del> or push
a manual reset. It never tries to load the kernel. Does not matter if
I try a 3.13.7 or 3.14.x, I've rebuilt them quite a few times and did
all the grub2 steps, but none of the newer kernels will boot.

Nothing was done to the bios. The only change was to get rid of ATI 
Frame buffer support as suggested upon a recent update:

* Checking for suitable kernel configuration options...
         *   CONFIG_FB_RADEON:    should not be set. But it is.
         * Please check to make sure these options are set correctly.
         * Failure to do so may cause unexpected problems.

stupid question i know but - was /boot mounted before doing the copies ?
you mention you have six other kernels on there -- could it be an out of 
disk / inode issue so it looks like it's copied but hasn't ?

please do copy the phrase to this list, I would be interested to know

from the grub2 menu can you choose your old kernels and boot them?
is it sitting waiting for you to press enter but perhaps there is a 
wierd usb-legacy thing in the bios preventing the keyboard working ?

does it appear to acknowledge the pressing of enter by not making you 
wait for the timeout and then just goes to a blank screen ? a flashing 
cursor ?

what about
# cat /etc/portage/make.conf
# gcc-config -l
# uname -a
# ls -lah /usr/src/linux/arch/x86_64/boot/bzImage

I was thinking maybe that you have made another change somewhere that is 
making the compilation of a new kernel skewiff... i.e. it's your 
compiler (build environment) not your grub that might be at fault

again stupid question but have you tried compiling with this option back 
in ?
i.e. could it be somehow silently booting but not updating the screen 
(clutching at straws i know)

I've had problems like this with grub2 when it was trying to retain the
graphics mode (sorry, I don't remember the line in grub.cfg since I've
since removed it.)

I usually find grub problems by entering the grub command line and
typing the commands in the menuentry from /boot/grub/grub.cfg that
doesn't work one at a time.

yep, this is what I suspect. I may need to reinstall grub2, for some
unknown reason. My research so far has yielded lots of anomolies with 
grub2....

Good idea, I'll try this.
