Anyone can test the patch in the Comment #34 ? From my opinions, this problem
is caused by wmi driver's EC operation region handler doesn't support
read/write operation of longer than 8 bit data and return bad param error.
Device (SCM0)
{
Name (_HID, "pnp0c14")
Name (_UID, Zero)
...
OperationRegion (EC, EmbeddedControl, Zero, 0x0100)
Field (EC, ByteAcc, NoLock, Preserve)
{
Offset (0x2D),
T2D0, 1,
T2D1, 4,
T2D5, 3,
TD2E, 8,
TD2F, 8,
TD30, 8,
TD31, 8,
TD32, 8,
TD33, 8,
Offset (0x35),
