drivers/gpu/drm/nouveau/nouveau_drm.c it overflowed my kernel log over two days. Also makes the virtual terminal completely unusable without silencing the kernel. The function(macro?) used to print the messages is NV_INFO
Which GPU are you using? And which messages are being spammed? Usually the only messages being printed by Nouveau after the module was loaded are suspend/resume and error messages. Could you attach to the bug report the whole output of a boot where such spamming occurred?
I apologize for exaggerating the bug. It is not as severe as I described previously but more than a inconvenience. Here's the output of a dmesg from kernel 4.8: [18530.252836] ACPI: \_SB_.PCI0.PEG0.PEGP: failed to evaluate _DSM [18530.252839] ACPI Warning: \_SB.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20160422/nsarguments-95) [18530.252945] nouveau 0000:01:00.0: DRM: suspending console...

[64790.494342] nouveau 0000:01:00.0: DRM: waiting for kernel channels to go idle... [64790.494383] nouveau 0000:01:00.0: DRM: suspending client object trees... [64790.494697] nouveau 0000:01:00.0: DRM: suspending kernel object tree... As you can see, nouveau is printing a lot of messages. I understand that this is intended behavior but I have both the nouveau log level and max log level set to 0 in the kernel config. I would appreciate it if you remove these messages, or at least add a option to disable them in the kernel config.
Oh, an Optimus latopt I guess, where the Intel GPU is the main one? Having a look at the source code, it appears that all the `NV_(FATAL|ERROR|WARN|INFO|DEBUG)` macros do not take into account the Nouveau log level and max log level variables, but only the kernel log level. I am not sure if it was meant to be that way, or someone forgetting to update those macros / switch to the new ones which respect the specified log level. Maybe all those suspend/resume messages shouldn’t be marked as info level, and could be moved to debug instead. I’ll ping Ben (the Nouveau maintainer) about it. (FYI, the Nouveau bug tracker is at https://bugs.freedesktop.org/, see https://nouveau.freedesktop.org/wiki/Bugs/)
Those messages are now debug messages, see commit [4cc5b39f][]. This bug report can be closed as fixed; it doesn’t look like the patch will be in 4.13, so it will most likely be part of 4.14. 4cc5b39f: https://github.com/skeggsb/nouveau/commit/4cc5b39f0fd4d1f3975f27eb190c241a7218a892
