2.6.39.2: duplicate filename '/devices/platform/GHES.9' on Asus DSBV-D

2.6.39.2: duplicate filename '/devices/platform/GHES.9' on Asus DSBV-D

On newly updated kernel I found this. I'm not sure it's a BIOS bug or
kernel bug. More infomation attached. I can gather more infomation if
you want :)

BTW, I used kexec to restart.
kexec -l /boot/vmlinuz-2.6.39.2 --append="ro root=/dev/sda1
rootfstype=ext4 quiet"
kexec -e

Deselect of "Power management and ACPI options ->
ACPI (Advanced Configuration and Power Interface) Support ->
ACPI Platform Error Interface (APEI)" avoided this message.

We had this issue already: http://lkml.org/lkml/2010/9/17/116 - I
guess the fix wasn't complete. And yes, it is a BIOS bug but the
kernel shouldn't OOPS just because BIOS programmers fell asleep on the
keyboard.

Adding some more people to Cc.

It's not oopsing, sysfs is spitting out a warning and then continuing
on, after failing to create the directory.

This bug has been reported and resolved in following bugzilla entry already.

https://bugzilla.kernel.org/show_bug.cgi?id=37412

We have the bugfix patch, just have not made it into upstream yet.
