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

[Drunkard Zhang]

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.
