Subject: Lots of "EDD information not available" messages

Hello,

running X86-64 on Intel motherboard DL87-RH with Opensuse-12.3 results in
lots of messages like

kernel: [ 459.263752] BIOS EDD facility v0.16 2004-Jun-25, 0 devices found
kernel: [ 459.263753] EDD information not available.
...

until I rename edd.ko. This happens still with "kernel of the day"
3.12.0-rc3-6.g9f1b1d6-desktop.

dmidecode list EDD:

Handle 0x0000, DMI type 0, 24 bytes
BIOS Information
...
EDD is supported
...

so I guess this is the reason why probably sysfs tries to load
edd.ko. However

edd_init(void)

sees ZERO devices and so denies to load.

if (!edd_num_devices()) {
printk(KERN_INFO "EDD information not available.\n");
return -ENODEV;
}

Probably the next action on sysfs tries to load edd.ko again. It this a
resonable explanation? What to do against it?

Thanks
