Argument #4 type mismatch #98

Lenovo Z50 laptop with Intel 4400 and nvidia 820M. I get the following warnings when enabling bbswitch, although it does power down the discrete card. The issue I'm having is resuming from standby sometimes fails, but that's more of a kernel issue I think.

The mismatching argument warning is harmless, it happens because NVIDIA designed an interface that violates the ACPI standard (but since they control both the firmware and driver, it does not cause other issues).

Please bring your issue to the intel graphics developers (intel-gfx@vger.kernel.org), they seems to be more appropriate for your issue.
