[SOLVED] switch Huge SMP to Generic

czezz · 06-02-2011, 03:35 PM

I have installed Slack 13.37 for test on VMware.
I installed just all - also all avalible distro. kernel imiges:

Code:

vmlinuz-generic-2.6.37.6
vmlinuz-generic-smp-2.6.37.6-smp
vmlinuz-huge-2.6.37.6
vmlinuz-huge-smp-2.6.37.6-smp

and the default is vmlinuz-huge-smp-2.6.37.6-smp.
Im trying to switch to vmlinuz-generic-2.6.37.6

So, what I did:
fs = ext4
root fs = /dev/sda1

Code:

/boot#  mkinitrd -c -k 2.6.37.6 -m ext4 -f ext4 -r /dev/sda1

Edited lilo: pointing new image, lilo command executed.
Every time I start new kernel i got this error:

Anyone knows what is wrong ?

look for a script called mkinitrd_command_generator.sh
it's on the slackware dvd in /source/a/mkinitrd/ directory
it detects what modules you should pass to mkinitrd

Looks like you haven't installed the kernel modules package.
kernel-modules-2.6.37.6-i486-2.txz

czezz · 06-02-2011, 04:10 PM

nivieru: it suggested to add jdb2 and mbcache, which are added by default any way - still not working. This same error

vulcan59: As I have written, I installed all - kernel-modules-2.6.37.6-i486-2.txz is included in all.

nivieru · 06-02-2011, 04:30 PM

did you also add

Quote:

initrd = /boot/initrd

to lilo?

czezz · 06-02-2011, 04:37 PM

Yes, did it previously.
Anyway, I just run script you told me before once again. This time more modules:

Code:

mkinitrd -c -k 2.6.37.6-smp -f ext4 -r /dev/sda1 -m mptbase:mptscsih:mptspi:jbd2:mbcache:ext4 -u -o /boot/initrd.gz

... and it is bootable now

Thanks!

I have the same problem. After excuting /usr/share/mkinitrd/mkinitrd_command_generator.sh I get the following command:

Code:

mkinitrd -c -k 2.6.37.6 -f ext3 -r /dev/sda1 -m usb-storage:xhci-hcd:usbhid:ehci-hcd:mbcache:jbd:ext3 -u -o /boot/initrd.gz

but after executing it and configuring lilo I cant boot and get the same error as post #1

Please help!

The relevant section of your /etc/lilo.conf file should read as follows:

Code:

# Linux bootable partition config begins
image = /boot/vmlinuz-generic-smp-2.6.37.6-smp
  initrd = /boot/initrd.gz
  root = /dev/sda?
  label = Slackware_Linux
  read-only  # Partitions should be mounted read-only for checking
# Linux bootable partition config ends

Substitute your root partition number in the line "root = /dev/sda_" and run lilo after the file has been edited.

My lilo.conf looks like this:

Code:

 image = /boot/vmlinuz-generic-2.6.37.6
 initrd=/boot/initrd.gz
  root = /dev/sda1
  label = Linux
  read-only
# Linux bootable partition config ends

There are no smp in the image name but it is what I have in my /boot/ dir after excuting the script.

In the initrd line, you need a space before and after the = sign.

I must also mention that when I execute lilo after changing lilo.conf I get a warning saying "lba32 addressing assumed"
I searched about it but I don't understand how to get rid off this warning.

brianL · 07-06-2011, 06:18 AM

Put lba32 in the global options in lilo.conf:

Code:

# Override dangerous defaults that rewrite the partition table:
change-rules
  reset
lba32
# Normal VGA console

Hi FrazAQ:

Here is a great link for setting up Slackware: http://genek.net/LinuxAdventures/sysadmin/index.html

HTH,

Thanks guys! It is working now, I added the spaces.
Also I think I added lba32 at wrong place before and it was not being accepted.
I am on generic kernel now

I hope this solves my problems.

mutexe · 07-07-2011, 04:57 AM

Sorry for the slight hijack. I want to switch away from the huge kernel, but dont actually use lilo (cuz ubuntu was on the machine first to be honest).
Can this all be done using grub? or am i stuck with huge?
Thanks, and sorry again,

Tom
