[gentoo-user] grub boot problem

[gentoo-user] grub boot problem

[Matthew R. Lee]

I've just compiled a new kernel, but when I reboot grub will not load the new 
kernel. I get error 15 (file not found). But the file is there.
Yes grub is install properly and yes the boot partition was mounted when I 
copied the new kernel across and changed the grub.conf. What's really 
confusing me is there's no syntax error in the grub.conf that I can see, and 
the first kernel on the list boots fine.  Anyone got any cluse as to why grub 
can't see the second kernel?

[grub.conf]
default 0

timeout 30

splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title=Gentoo 2.6.22-r2

root (hd0,0)
kernel /boot/kernel-2.6.22-r2-2 root=/dev/sda3 
video=vesafb:mtrr,ywrap,1280x800-24@70

title=Gentoo 2.6.24-r8

Could you please show us:

$ mount

and 

# ls -la /boot

I should probably give /boot a clean, but could this be the problem?

According to your grub.conf your default is the top entry, but the 
kernel image for that doesn't exist in your boot partition.

kernel /boot/kernel-2.6.22-r2-2 root=/dev/sda3

should probably be

kernel /boot/kernel-2.6.22-r2 root=/dev/sda3

Thats if 2.6.22-r2 is the kernel your trying to boot.

Hi,

Another thing you can try is tab completion in the grub menu.  Just hit 
the "e" key twice and let grub help you with what kernels it can see. 

Hope that helps.

This is wierd, I hadn't noticed that, but that's not causing the problem.
I'm running the 2.6.22-r2 kernel now, that's the one that boots, the 2.6.24-r8 
is the one grub can't find.

Re: [gentoo-user] grub boot problem

[Volker Armin Hemmann]

one question:

why don't you use 'make install' and have a 'vmlinuz' and 'vmlinuz.old' entry 
in menu.lst/grub.conf?

that solves/prevents lots of errors.

Ok,
I figured out the problem, but no why it's happened. If you look at the output 
of ls -la /boot there is another folder /boot and within this a symlink /boot 
(./) By copying the kernel to this folder and modifiying the grub.conf in the 
associated /grub folder the the new kernel boots.
Question is how did I come to have a cascade of boot folders and how do I get 
things back the way they should be?

Don't know how you got there, but to get things back to normal you should 
remove /boot/boot and make it a symlink to /boot:

cd /boot
rm -rf boot
ln -s . boot

I would also revise grub.conf a bit:

default 0
timeout 30
root (hd0,0)
splashimage=/grub/splash.xpm.gz

title=Gentoo 2.6.22-r2
	kernel /kernel-2.6.22-r2 root=/dev/sda3 
video=vesafb:mtrr,ywrap,1280x800-24@70  <- On one line, of course

title=Gentoo 2.6.24-r8
	kernel /kernel-2.6.24-r8 root=/dev/sda3 
video=vesafb:mtrr,ywrap,1280x800-24@70

Optionally, you could also reinstall grub to your MBR, by running grub (or was 
it grub-shell?) and issue the following commands:

root (hd0,0)
setup (hd0)

HTH...

If hd0,0 is your boot partition, you shouldn't have /boot in the kernel
line, just

kernel /kernel-2.6.22-r2-2 root=/dev/sda3 

In GRUB, all paths are relative to the root.

really? I boot this for years, after nothing else worked:

title=2.6
root (hd0,0)
kernel (hd0,0)/boot/vmlinuz root=/dev/sda3 nmi_watchdog=0

Hmm, have you this in place?

lrwxrwxrwx  1 root root   1 Mar 26  2006 boot -> .

Hmm, you should usually be able to transform this to:

root (hd0,0)

title=whatever
	kernel /vmlinuz root=/dev/sda3 nmi_watchdog=0

What's this nmi_watchdog=0 good for (just curious)?

So that people who can't wrap their brains around how grub works (i.e. 
it is NOT linux) can get the thing to work. So

kernel /boot/vmlinuz root=...
will boot, as well as
kernel /vmlinuz root=...

to make sure it is off ;)

I once read (also a long time ago) that the nmi-watchdog could/would/does slow

in theory it should be able to 'break' some kinds of lockups.

just read this:
/usr/src/linux/Documentation/nmi_watchdog.txt

its a good read.
