Bugzilla Bug 133936

Since I've upgraded to udev-0.90 gentoo-sources-2.6.16-r7 the svgalib_helper
module refuses to load after successful compilation.

output of modprobe:

WARNING: /etc/modprobe.conf line 100: ignoring bad line starting with
'probeall'
FATAL: Error inserting svgalib_helper
(/lib/modules/2.6.16-gentoo-r7/misc/svgalib_helper.ko): Invalid argument

output of dmseg:
svgalib_helper: falsely claims to have parameter all_devices

There's also no /dev/svga being created

emerge --info

I'm having the same trouble, but I'm not sure if it is related
to udev (in fact, I'm using udev-087)

modprobe svgalib_helper

gives the message

FATAL: Error inserting svgalib_helper
(/lib/modules/2.6.16.18/misc/svgalib_helper.ko): Invalid argument

I'm using linux-2.6.16.18 (with 2.6.16 headers) on a Gentoo x86 host.
module-init-tools-3.2.2 (I've tested it also with 3.2.1)
glibc 3.2.1 gcc-4.1.1 binutils-2.16.1

and dmesg muestra el mensaje

svgalib_helper: falsely claims to have parameter all_devices

In fact, I've also tried udev-079-r1 (the version that I was using
before the upgrade), and it didn't work either.
In my opinion, this issue is related to the upgrade of binutils.
Which version of binutils are you using?

binutils-2.16.1-r2 marked x86 stable

I've suceded to load svgalib_helper into the 2.6.16.18 kernel
by comenting out the lines declaring the all_devices parameter
in /kernel/svgalib_helper/main.c and building the module from
the source:

MODULE_PARAM(all_devices,"i")
MODULE_PARAM_DESC(all_devices,....)

Of course, this is just a temporary work around if you don't really
need the all_devices parameter.

a mistake in my previous report: I'm using glibc-2.4
and svgalib-1.9.24

I've succeded in fixing this bug!

The solution is very simple: remove the static keyword in the line

static int all_devices=0;

in kernel/svgalib_helper/main.c

(this causes the symbol not to be exported by the linker)

I'm submitting a patch for this issue. Since don't have write access, please
someone add this patch to portage.

fix looks good to me ... could you e-mail this to the upstream author please ?
