[Nouveau] Fans ramping up randomly when idle

[Timothy Madden]

Hello

My Msi Gaming X Trio 2080 Ti randomly ramps up the fans with no way to recover
(I have to reboot) even when the card is idle or is only showing the desktop.

This issue happens even when the card is not connected to a monitor.

My dmesg output from nouveau is included below, I think the last 2 lines are
the relevant ones:
[ 9426.768449] nvidia-gpu 0000:0b:00.3: Unable to change power state from D3hot to D0, device inaccessible
[ 9427.889387] nvidia-gpu 0000:0b:00.3: i2c timeout error ffffffff
