I'm running Ubuntu 16.10 on a Lenovo Z510 with gt 740m. Using any NVidia driver, when I try to wake up from suspend the screen is black and an error is displayed:

[ 1046.061495] [drm:wait_panel_status [i915]] *ERROR* PPS state mismatch
[ 1047.081663] [drm:hsw_write_dcomp [i915]] *ERROR* Failed to write to D_COMP
[ 1047.369023] NVRM: Xid (PCI:0000:07:00): 70, GPU has fallen off the bus.
[ 1046.061495] [drm:wait_panel_status [i915]] *ERROR* PPS state mismatch
[ 1046.061495] [drm:wait_panel_status [i915]] *ERROR* PPS state mismatch

When I was on Ubuntu 16.04, the same problem occurred, but the screen was completely black, without the error.

Due to acpi BIOS incompatibilities, the Z510 needs an additional kernel commandline parameter acpi_osi="!Windows 2013" for suspend/resume to work.

See: https://github.com/Bumblebee-Project/bbswitch/issues/142

The drm:wait_panel_status has been appearing since kernel 4.8 but so far I haven't notice any negative effects.

As per Xid errors list (check PDF), the error 70 (CE3: Unknown Error) is related to driver or hardware issue. Try upgrading your driver to the latest version.

For different error such as 79, check: NVRM: Xid: 79, GPU has fallen off the bus.
