Hi Nouveau Devs,
I have Nvidia 940MX graphics card on an i7 laptop.
I am observing below errors when i start Fedora and view the logs, but
didnt take them seriously. (my bad)
I am facing random crashes with i play certain (not all) games in (dual
boot) windows 10, and maybe there is a connection with the error emitted by
nouveau driver.
Any help in understanding the meaning of logs and how to fix it would be
appreciated.
Pasting the logs below
$ dmesg --raw | grep -P "(nouveau|pcieport)"
