[FC5] Upgrading kernel and sources safely?

[littlebigfred]

Hello

I'm about to install FC5 using the first CD and download the rest of the stuff from the Net.

Problem is, it appears that FC5 has a bug when trying to compile the Zaptel module that is used by the open-source PBX Asterisk to use an FXO card to connect it to the phone network:

Fedora Core 5 - Zaptel will not compile against the stock FC5 kernel, due to a bug in the kernel. You will get an error message like "module format invalid" when you try to modprobe the zaptel modules.

To make zaptel work with FC5, download an updated kernel. (As of 27 March 2006, the updated kernel has not yet been released, but can be downloaded from http://download.fedora.redhat.com/pu...tes/testing/5/.

You'll want the get both the kernel and kernel-devel RPMs for your particular architecture.) -jsmith

Does it mean that I can just download the two RPM's (kernel-devel-2.6.17-1.2139 and kernel-2.6.17-1.2139) from Fedora's site, do the usual rpm -Uvh, reboot, and choose the new kernel in the bootloader... or is it more involved?

Thank you.

if you are connected to the internet, you can update the kernel and kernel-devel by typing

yum update kernel

as root. If you arent net connected then yes, just download the rpms. Although that may cause dependency errors which means you will need updated rpms of everything that conflicts. Yum handles that for you, so do it that way if you can

Thx for the tip!

"yum update kernel" and "yum update kernel-dev" seem to have installed OK (from 2.6.15 to 2.6.17), but I get an error when compiling the zaptel source:

Anybody knows what I need to do? Do I need to reboot and choose the 2.6.17 kernel that I assume yum added to Grub?

Thank you.

Reboot to the new kernel before building.

Thx, that helped. There was also a bug in the "build" symlink iunder /lib/modules which prevented from compiling zaptel.

Unfortunately, I can't load the module:

Any idea?

Found it: Kernel was for i686 and kernel-devel was for i586. Removed, downloaded the right version, compiled, loaded driver, done.
