I guess you're referring to this in iwl_request_firmware()?
IWL_ERR(drv, "check git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git\n");
How can we fix this in nouveau so we don't have the debug this again?
I don't really know how firmware loading works, but "git grep -A5
request_firmware drivers/gpu/drm/nouveau/" shows that we generally
print something when request_firmware() fails.
But I didn't notice those messages in your logs, so I'm probably
barking up the wrong tree.

So maybe the wakeups are related to having vs not having the nouveau
firmware? I'm still curious about that, and it smells like a bug to
me, but probably something to do with nouveau where I have no hope of
debugging it.

Nope, don't bother with this, thanks.
