Bug Description
When initiating suspend (to RAM), the kernel gets tainted. This is a regression that appeared after upgrading from Kubuntu 13.10 to 14.04. My computer has a discrete nVidia G210M card (hybrid SLI system, on ASUS UL80VT). Here is an extract from dmesg:
PM: Preparing system for mem sleep
BUG: unable to handle kernel NULL pointer dereference at 00000000000000b8
