OpenIndiana/Solaris / Lenovo P52 / Quadro P1000 Mobile / Failed to copy vbios to system memory

Hi,

I’m having issues with the NVIDIA drivers on my Lenovo P52 on OpenIndiana (OpenSolaris fork).
The drivers do work, as I see on my Dell Precision 7560 with another Quadro card. However in this Lenovo I get:

I tried to vary different BIOS setup settings, and I ensured that Discrete Graphics is selected.
However I always get this error. I also tried to boot with ACPI=legacy, but also that changed nothing.

I’m happy to provide the nvidia-p52-bug-report.log.gz here, and also willing to provide more debug output if requested.

In hope for some help,
