klog: HIGH Kernel message: [    7.944886] ACPI Warning:
\_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer],
ACPI requires [Package] (20140424/nsarguments-95)

for _DSM failure, kernel compliant about the mismatch of _DSM method(Device Specific Method)
>From ACPI spec,
This optional object is a control method that enables devices to provide device specific control
functions that are consumed by the device driver.
Arguments: (4)
Arg0 – A Buffer containing a UUID
Arg1 – An Integer containing the Revision ID
Arg2 – An Integer containing the Function Index
Arg3 – A Package that contains function-specific arguments

the #4 Arg (i.e Arg3 is defined as a Package) , but seems the graphic driver bright an Buffer to it.
This has often been seen on the graphic driver, since the _DSM is device specific method. 
This shouldnot be a problem if the graphic function is fine.

Title:
  [Lenovo W550s] 'Run Firmware Test Suite (fwts) desktop-specific
  diagnosis tests' test case is always fail.

Status in HWE Next Project:
  Won't Fix
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  CID : 201412-16338 Lenovo W550s (I+N) with 14.04.2 (utopic)

  Steps:
  1. Install 14.04.2 on W550s
  2. Install Plainbox and run test case 'Run FWTS desktop-specific diagnosis tests.'

  Expected result:
  Test result should be pass.

  Actual result:

  ==================
  ADVICE: Test caused CPU temperature above critical threshold. The CPU has been
  throttled to run slower because of over-heating above the critical threshold.
  CPU throttling will be turned off once the CPU has cooled sufficiently. Frequent
  throttling may indicate poor thermal design on the machine.
