dmesg log of kernel entries

Hi,

I'm currently having an issue while trying to use my discrete card GTX1050TI on my laptop Acer Predator PH317-51 under QubesOS with any kernel (e.g. 4.14+ and 4.16+, the current one is 4.16.9). In order to boot, I have to set nouveau.modeset=0 but I cannot use my HDMI output because it is not detected and it seems that the HDMI port is wired to the NVIDIA card. If I remove this option in the grub conf, and I plug my second screen on the HDMI port, at the boot process, I'm having error such as (full dmesg log is attached):

And I finally end with a kernel panic. If I don't plug my second screen on the HDMI port, I can boot but the Xserver crashes when trying to log in XFCE session. I also tried to restrict the xrandr settings at the login session without any success. Please note that it has nothing to do with QubesOS as I tested and encountered the same problem with a fresh up to date Fedora 28.

If some of the developers of the nouveau driver can oriented me where to dig in the source code, I would be please to learn and do some tests or patches, even for helping in the future.

Thank you in advance for any help.
Frédéric

Please check if nouveau.runpm=0 helps
