Description:   Opened: 2004-05-13 02:18 0000 
The svgalib_helper.ko module is not loadable on 2.6.6 kernels. The error when
issueing a `insmod svgalib_helper.ko' is `invalid module format'.


Reproducible: Always
Steps to Reproduce:
1. execute `emerge =media-libs/svgalib-helper-1.9.18-r1
2. execute `modprobe svgalib_helper'


Actual Results:  
Error: Invalid module format

Expected Results:  
nothing, issueing `lsmod' would have had to produce a list with libsvga_helper
in it.

A solution is to make sure that svgalib-1.9.18-r1/kernel/Makefile is executed
instead of svgalib-1.9.18-r1/kernel/Makefile.alt.

For me this solved the problem.

I use module-init-tools 3.0 from module-init-tools-3.0-r2.ebuild
With a vanilla 2.6.6 kernel.

what if you run `modinfo` on the module after building with the ebuild ?

when you used the Makefile, did you do so with the ebuild, or did you build it yourself ?

Hello,

i have the same problem. I use the kernel from the development-sources-2.6.6. Svgalib-1.9.17-r3  and also the "unstable" svgalib-1.8.18-r1 have emerge perfectly, but when i try to modprobe or insmod the module libsvga_helper i get the message:

insmod: error inserting '/lib/modules/2.6.6/misc/svgalib_helper.ko': -1 Invalid module format

The modinfo command produce only this:

license:        GPL and additional rights
author:         Matan Ziv-Av <matan@svgalib.org>
description:    Generic hardware access to vga cards

The effect is, that the kernel-udev can't create the /dev/svga device.

The module was produces with the regular ebuild. I don't have compile it manualy. 

Is more information needed?

it's the new kernel stuff ... since nvidia-kernel seems to do it properly now,
i'll see how it works

------- Comment #6 From SpanKY 2004-05-29 23:12:18 0000 ------- 
should be fixed in 1.9.18-r1
