General :: Kernel Upgrade / Saying "No Modules"?

Feb 25, 2010

Recently I downloaded the latest 2.6.33 kernel from I had earlier 2.6.29 kernel version installed through Fedora 11 Leonardos.I followed simple steps through url.html and it went fine.I could see new Kernel during grub.conf splash display during dual-boot option.But there are few doubts like as shown below:

Compiling module in Linux:
$cd /usr/src/linux-2.6.33
$make menuconfig
HOSTCC firmware/ihex2fw

though the process went fine....Is it fine with the last line?Though I can easily boot into New Kernel and can see everything there. why it says "No modules.."

Also, Just for information - "Why we compile kernel?Say I have two kernels now- 2.6.33 and 2.6.29. Whats the difference?

Apr 10, 2011

I upgrade my slackware to slackware-current. But, when I look /etc/rc.d/rc.modules, it's still symlink to old kernel. Is this normal? Or i must change the symlink manually?

OpenSUSE :: Can't Recompile Virtualbox Kernel Modules After Upgrade To 11.4?

Mar 20, 2011

This has got me stumped. I expected to do /etc/init.d/vboxdrv setup after the upgrade from 11.3 to 11.4 but the command fails. The log is (it seems to repeat so I only quote the final bits to make it fit into the wordcount limit):

I tried to look into the directory and there was only modules under So I tried to change the command into: Quote: mkinitrd -c -k -m ext3 -f ext3 -r cryptroot -C /dev/sda2

This command was successful, but I don't know if this is alright. I made the changes in lilo.conf, add initrd = initrd.gz. This is all on unencrypted /boot partition. The boot=/dev/sda1 I also set for the unencrypted boot partition. When I boot the system I get a kernel panic:

General :: New Kernel Only Has Two Modules?

Sep 26, 2010

I have just compiled a new kernel. When I boot into this new kernel and do an lsmod it is only running two modules. The only thing I changed in the configuration file was to compile ext4 file system into the kernel. My computer is an HP Pavilion dv4. The two modules are lirc_ene0100 and lirc_dev. I am running Ubuntu 10.04. The new kernel is The kernel seems to work fine but I need to know why and how it can only be running two modules.

It has been years since I have need to compile the kernel or its modules. Here goes: I recently upgraded to ubuntu 10.10 and needed the kernel source and its modules source. The relevant directories are in a mess. Several diff versions, broken links, the works. Is there a nice easy way, to remove all of the sources, there, and err "install" the ones for my latest kernel, in the correct places. Then I might have a chance at getting the two modules I need complied! Nvidia being one for the geforce 4 mx420 nv17

General :: Compiling New Kernel - List Of Current Modules

May 25, 2011

I'm trying to compile a kernel for my Crux Linux install. I figured I'd do a 'make defconfig' to setup a .config file with the default configuration and then try to add anything I will need for my specific system. I found a script that scans my system and prints out a list of any current modules I am using. That way I can make sure to add these to my new kernel. It looks something like this:


Is there a way to add these to my current configuration without having to go into 'make menuconfig' and search for each one? It's not too hard to search for many of them. But the ones with short names I'm not finding. Like ac.ko for example. 'ac.ko' returns 0 search results and 'ac' returns anything and everything with those 2 letters in it.

General :: Kernel 3.0-ARCH VMWare Modules Wont Build

Aug 4, 2011

Since new kernel 3.0 update I cannot rebuild vmware modules


sudo vmware-modconfig --console --install-all Unable to initialize kernel module configuration

how to do that. Where do I insert the "CONFIG_LOCALVERSION" line.


Same here. This seems to be due to the kernel version being "3.0" instead of "3.0.0". Recompiling the Kernel (and all modules based on it, e.g. nvidia) with
CONFIG_LOCALVERSION=".0-ARCH" allows me to compile the modules and run VMware.

General :: Loaded Kernel Modules On Virtual Server And CSF Confusion

Dec 24, 2010

what is happening on my Centos virtual server (ps I'm having a great time re-learning Linux after a large gap and usually try and find out myself but this has me confused) First thing I did was install Tomcat and try and change the port to 80 using iptables -nat and it complained a kernel module was missing. Instead setup Apache to redirect requests so that's now working I then tried to install CSF firewall and the validation perl script returned fatal errors so I assumed OK my virtual server Kernel is restricted and used denyhosts instead which is working great

Here's the confusion.. I later retried the csftest script and it now works including all the iptables and nat stuff that fataled before. I've not rebooted or changed anything except run denyhosts and the postgres daemon + ended a few daemons that I didn't need (eg pickup,tlsmgr,courier,postfix,qmgr,saslauthd) Running lsmod returns nothing and /proc/modules is zero bytes so I'm not able to tell what is loaded? I'm tempted to try and get Tomcat redirecting via iptables and see what happens but if it works I don't like that something seems to have changed.. before I ran it direct as root now I'm SU into root from another login

General :: Rc.modules Not Loading Modules At Startup?

May 11, 2010

I've been trying to load my pcmcia network card driver "xirc2ps_cs" at startup with no success. I have added "modprobe xirc2ps_cs" to the rc.modules file but it doesn't load at startup. Curiously, though, if I execute rc.modules AFTER the machine has booted it will load the modules just fine. Just not during the boot up process. Thinking that hotstart might have been causing problems I've disabled hotstart (chmod -x) temporarilly to remove it from the picture, but there was no change.

Programming :: Using SIGNALS In Kernel Modules?

Apr 23, 2010

I am writing a kernel module which need to do something at some interval. Now this problem can be solved by using a user process, which will send signal to the kernel and the kernel would do accordingly. But it would be nice, i could do it within the kernel module itself. Is there any way to use SIGNALs inside the kernel module?

Ubuntu :: How To Write The Kernel Modules

I am trying to write kernel modules. And am running Ubuntu 10.04 x64. I have downloaded both kernel source and headers. Unpacked kernel source and made a /usr/src/linux symbolic link pointing to the src. Here is the output of running make:


make -C /lib/modules/2.6.32-22-generic/build M= modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.32-22-generic'

I am taking both the module and the Makefile from Linux Kernel Module Programming Guide book. I don't know what am missing.

Fedora Installation :: New Kernel Will Not Boot (Modules)

Mar 26, 2011

The new kernel upgrade on Fedora 14 will not boot. lib/modules do not exist is the message. Grub was adjusted to match the old kernel, and the new kernel when booting says lib/modules do not exist. The old kernel has twice as many modules as the new kernel in lib/modules. How do I get the new modules to install so I can boot with the new kernel then? Should I reinstall the new kernel?

Software :: Recompiling Kernel Required To Add Modules?

Jan 4, 2011

I only have basic experience recompiling a Linux kernel, and I have a question about adding dynamic modules.In case I want to add a brand new module, do I need to recompile the kernel to include a reference to that new module, or is simply compiling a kernel with generic support of dynamic modules all it takes to add whatever modules I need later on, without recompiling the kernel and rebooting the host?

Slackware :: Missing Kernel-modules Package

Feb 11, 2011

I upgraded to the latest -current just like always. I do the kernel packages last. This time, the machine failed to boot, telling me that it could not find the kernel modules. Well, rats.

I booted with a slackware dvd, passed the huge.s kernel, and booted into /dev/sda7, which is my main partition. I mounted /dev/sda7, and installed the kernel-modules- pkg. Rebooted, and got the same error?

I booted again with the dvd, mounted the partition, and navigated to /lib/modules - no in there!

How do I get that package to install?

Debian Configuration :: Kernel Modules Won't Load Anymore

Jul 7, 2015

After a hiatus I found my machine to be down, but upon turning it on I get significant errors and dropped into emergency mode (see below). This machine wasn't very up-to-date to begin with, so I'm having difficulty determining the order in which to proceed. A couple naive checks and updates on my part are not working. The file system appears to be intact enough to "cd" around and "ls" to see that my files are all (seemingly) there. But the kernel modules aren't loading which is, you know, a problem.

The state I find it in is that it will begin booting to Linux 3.2 (which I know is no longer supported in testing, see below where I tried to update to 3.16), but fails quickly and puts me into emergency mode

Loading, please wait...
megasas: INIT adapter done
systemd[1]: Failed to insert module 'autofs4'
systemd[1]: Failed to open /dev/autofs: No such file or directory
systemd[1]: Failed to initialize automounter: No such file or directory
systemd[1]: Failed to set up automount Arbitrary Executable File Formats File System Automount Point.

...Then several drives show up as clean....

Running "journalctl -xb" shows that it can't mount the module even though it's there on the disk:
... systemd-modules-load[259]: could not open moddep file '/lib/modules/3.2.0-4-amd64/modules.dep.bin'
... systemd-modules-load[259]: Failed to lookup alias 'firewire-sbp2': Function not implemented
... systemd-modules-load[259]: could not open modeep file '/lib/modules/3.2.0-4-amd64/modules.dep.bin'
... systemd-modules-load[259]: Failed to lookup alias 'loop': Function not implemented

And yet, if I 'ls' that modules.dep.bin file, it's right where it's supposed to be, for the appropriate architecture and everything.

After that (in the journalctl output), it shows several things start up, but systemd-modules-load.service fails:
.. systemd[1]: systemd-modules-load.service: main process exited, code=exited, status=1/FAILURE
.. systemd[1]: systemd-modules-load.service: Failed to start Load Kernel Modules

...and lots of things fail from systemd-udevd: failed to execute '/lib/udev/socket:@/org/freedesktop/hal/udev_ev_event': No such file directory.

"uname -a" shows
Linux <my hostname> 3.2.0-4-amd64 #1 SMP Debian 3.2.32-1 x86_64 GNU/Linux

I tried updating via apt to the Linux 3.16.0 kernel, but grub wasn't finding it in a way that effects the boot process, and no appropriate "vmlinuz-" file appears with the others on the boot partition. So, I tried switching to grub2 but the update-grub command produces many errors.... For now, grub2 still (attempts to) load the old kernel (3.2) with the same results as I was getting with the old grub-legacy.

Regarding the module-loading features, running "lsmod" shows about 30 lines:


[Code] ....

...I'm at the limit of what I know to check and/or try.
