nvkm_pmu_reset issue with Optimus card

[Denis Fateyev <denis@xxxxxxxxxxx>]

Hello there,

I have got an Asus notebook with Optimus technology support on board:

$ lspci -vnn | grep '\''[030[02]\]'
00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 530 [8086:191b] (rev 06) (prog-if 00 [VGA controller])
01:00.0 3D controller [0302]: NVIDIA Corporation GM107M [GeForce GTX 960M] [10de:139b] (rev ff) (prog-if ff)

My system is a fully updated Fedora 30 with the kernel version 5.2.9.

The problem is that every time when "nouveau" is activated the system hangs shortly with multiple dumps in dmesg.

I have already reported the issue to RHBZ [1], as I have understood this is a known issue.

Practically, I can bring it up with Bumblebee + Intel + proprietary drivers + acpi_osi='Windows 2009', but instead I would like to get the Intel + Nouveau solution working.

Are there any fixes or ideas on how I could achieve that?

I could help with more testing the issue if needed.

Thanks,
