While I had thought I had fixed this issue in: commit 342406e4fbba ("drm/nouveau/i2c: Disable i2c bus access after ->fini()") It turns out that while I did fix the error messages I was seeing on my P50 when trying to access i2c busses with the GPU in runtime suspend, I accidentally had missed one important detail that was mentioned on the bug report this commit was supposed to fix:

For a while, we've had the problem of i2c bus access not grabbing a runtime PM ref when it's being used in userspace by i2c-dev, resulting in nouveau spamming the kernel log with errors if anything attempts to access the i2c bus while the GPU is in runtime suspend. An example: [ 130.078386] nouveau 0000:01:00.0: i2c: aux 000d: begin idle timeout ffffffff Since the GPU is in runtime

Sadly, there are elements (hello "gentoo"!) that, during the cleanup.d phase, wipe out almost everything in the /tmp of the guest, including the /tmp/aux where virt-dib mounts the auxiliary data. Since that removal excludes things starting with "in_target" (mostly to avoid wiping the "in_target.d" that disk-image-create itself sets up, then rename our "aux"

Currently the work around seems to be to add i8042.noaux to the kernel command line. If someone wants to investigate, please do so. As secondary problem I think it would be wise to put a big f*cking warning that Xen + Linux + GCC 4.2+ is one big problem.

I need to ask, to refresh, is the aux power connector on the TDM400P card *only* to power the ringer on any analog phones/devices on the system? Can I still use this board, to "terminate" POTS lines and use all SIP Phones? Due to circumstances, I end up with a 1u server that has no aux power connectors available. I "have to" use this server, so am considering abandoning

From: Hans Verkuil <hans.verkuil at cisco.com> If aux->transfer == NULL, then just return without doing anything. In that case the function is likely called for a non-(e)DP connector. This never happened for the i915 driver, but the nouveau and amdgpu drivers need this check. The alternative would be to add this check in those drivers before every drm_dp_cec call, but it makes sense to
