Bug 77186 - Svgalib doesn't work with 2.6.10 kernel
Bug#: 77186 Product:  Gentoo Linux Version: unspecified Platform: x86
OS/Version: Linux Status: RESOLVED Severity: major Priority: P2
Resolution: FIXED Assigned To: kernel@gentoo.org Reported By: ltsiros@yahoo.com
Component: Core system

Summary: Svgalib doesn't work with 2.6.10 kernel
Keywords:  Inclusion
Status Whiteboard: 
Opened: 2005-01-08 16:48 0000
Description:   Opened: 2005-01-08 16:48 0000 
When I try to load the module svgalib_helper (essential for svgalib output), I
receive the following error:

bash-2.05b# modprobe svgalib_helper
FATAL: Error inserting svgalib_helper
(/lib/modules/2.6.10/kernel/misc/svgalib_helper.ko): Unknown symbol in module,
or unknown parameter (see dmesg)

and the message in dmesg is:

svgalib_helper: Unknown symbol devfs_mk_symlink

The kernel was patched with -ck2, but I don't think this has to do with -ck. I
reemerged svgalib with no success (both with USE="build" and USE="-build")

Reproducible: Always
Steps to Reproduce:
1.modprobe svgalib_helper
Actual Results:  
bash-2.05b# modprobe svgalib_helper
FATAL: Error inserting svgalib_helper
(/lib/modules/2.6.10/kernel/misc/svgalib_helper.ko): Unknown symbol in module,
or unknown parameter (see dmesg)

Expected Results:  
The module should be loaded

This happens to me as well, using a vanilla 2.6.10 kernel patched with
vesafb-tng.

Any news? If you want I can try the patches myself, just give me some hints on
how to patch what I have to patch ;)

Thanks for the work so far!

svgalib is not compilable anymore, since applying the patch fails ... :(

This is fixed in cvs, just emerge sync again :)
