Bug#380534: drm mach64 module compiled from dri cvs against linux-headers-2.6.17-1-686 fails to load

[Christopher OCallaghan <chrisoc@nerdshack.com>]

Package: linux-headers-2.6.17-1-686
Version: 2.6.17-4
Severity: normal


here is the error on the command-line when calling modprobe mach64:
FATAL: Error inserting mach64
(/lib/modules/2.6.17-1-686/kernel/drivers/char/drm/mach64.ko): Unknown
symbol in module, or unknown parameter (see dmesg)

Here is the output in dmesg:

I'm sure this is not a bug in the dri cvs, because I also built the same
module against the headers in a custom-compiled 2.6.17.3 downloaded from
kernel.org, and the module works fine with that kernel.

here is the procedure I used for fetching the cvs and compiling the module:
 git clone git://anongit.freedesktop.org/git/mesa/drm
 cd drm/linux-core
 make DRM_MODULES="mach64" LINUXDIR=/usr/src/linux
 (/usr/src/linux is a symlink to /usr/src/linux-headers-2.6.17-1-686)
 cp /lib/modules/2.6.17-1-686/kernel/drivers/char/drm/drm.ko
 /lib/modules/2.6.17-1-686/kernel/drivers/char/drm/drm.ko.orig
 cp drm.ko /lib/modules/2.6.17-1-686/kernel/drivers/char/drm/drm.ko
 cp mach64.ko /lib/modules/2.6.17-1-686/kernel/drivers/char/drm/mach64.ko
 depmod -a $(uname -r)
 modprobe -r drm
 modprobe -r mach64
 modprobe mach64
