Alex has analyzed this issue and does not think it really affects hybrid
graphics. Could you discuss with your team and see if we can close this issue,
or should we try to update the BIOS for further investigation?

Bug description:
Lenovo ThinkPad T440p ( CID 201309-14169 ) on Ubuntu 14.04
3.13.0-24-generic
----------------------------------------
fwts high failures were found as the following:
klog: HIGH Kernel message: [ 27.371715] ACPI Warning:
\_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI
requires [Package] (20131115/nsarguments-95)
klog: HIGH Kernel message: [ 29.882167] ACPI Error: Field [TBF3] at 270336
exceeds Buffer [NULL] size 262144 (bits) (20131115/dsopcode-236)
klog: HIGH Kernel message: [ 29.882172] ACPI Error: Method parse/execution
failed [\_SB_.PCI0.PEG_.VID_.GETB] (Node ffff8802333d1960), AE_AML_BUFFER_LIMIT
(20131115/psparse-536)
klog: HIGH Kernel message: [ 29.882179] ACPI Error: Method parse/execution
failed [\_SB_.PCI0.PEG_.VID_._ROM] (Node ffff8802333d1938), AE_AML_BUFFER_LIMIT
(20131115/psparse-536)
----------------------------------------
Steps to reproduce the bug:
1.on the power-saving mode (intel chip),
fwts found a klog high failure
klog: HIGH Kernel message: [ 26.704702] ACPI Warning:
\_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer],
ACPI requires [Package] (20131115/nsarguments-95)
by the command
fwts -q --stdout-summary -r <log file name> klog
2. switch to the nvidia graphic card via dash → nvidia setting → select nvidia
3. reboot to make the switching work
4. use the same fwts command and it will show the high failures. There are 3
more high failures found.
