Module cdrom not found

**roxy2** · June 12th, 2009

Hi,

I cannot mount my cdrom in Ubuntu 9.04.

I am running the following kernel:

Code:

uname -a
Linux amd-quad 2.6.28-13-generic #44-Ubuntu SMP Tue Jun 2 07:55:09 UTC 2009 x86_64 GNU/Linux

and I see there is no cdrom directory in /lib/modules/2.6.28-13-generic/kernel/drivers/

Thus I cannot modprobe the cdrom module:

Code:

modprobe cdrom
FATAL: Module cdrom not found.

I did not remove any packages in Ubuntu.
What is wrong; is there a bug in 2.6.28-13?

In ubuntu the cdrom drivers are built into the kernel and not as modules.

If you are having issues, it looks like you aren't the only one.

Thanks. So it is a bug?

I'm not entirely sure. If you have a cdrom drive and it's not working properly, you have a bug. But the missing module is not, it's just that the kernel team decided to build the driver directly into the kernel instead of having the driver as a module. This means that whenever the kernel is loaded, the driver should be in it. If it were a module, the kernel would load and then the module inserted at a later time.
