I have noticed several cases where, if I use lsmod to find a module and then use modinfo for that module, it comes out with a ERROR: Module not found message. For example with the Nvidia module (When using the proprietary drivers).
So in what cases would a module appear on lsmod but give an ERROR like the one I mentioned above with modinfo.
aks@aks-K55VD:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04.1 LTS
Release: 12.04
Codename: precise
used the command lsb_release -a
and found 'No LSB modules are available'
LSB->http://en.wikipedia.org/wiki/Linux_Standard_Base
what does that mean by the unavailability of this module and how can they be made available to my system?
I'm using hardware that requires a driver to be built which is not present in the kernel source tree, i.e. not "part of" linux. Currently I'm finding it necessary to rebuild and install the driver manually every time I start using a new kernel version. Is there a way to streamline this process?
When attempting to start the iscsitarget service, I get
FATAL: Module iscsi_trgt not found.
Trying to build module using instructions from http://sourceforge.net/apps/mediawiki/iscsitarget/index.php?title=Unofficial_DEBs fails and the build log only has a single line in it saying the build started. Nothing about the failure.
I am trying to build my own module for usbhid.ko, but after I compiled, I can't load the module. dmesg says no symbol version for module_layout. I am wondering what is the problem? I have already used the kernel source provided by Ubuntu and I have also make sure the kernel version is the same.
