[Nouveau] nouveau: DRM: failed to create ce channel, -22 on Jetson TK1

[Martin Michlmayr]

I see the following on a Jetson TK1:

[    9.495425] [TTM] Initializing DMA pool allocator
[    9.495513] nouveau 57000000.gpu: DRM: VRAM: 0 MiB
[    9.495520] nouveau 57000000.gpu: DRM: GART: 1048576 MiB
[    9.508076] nouveau 57000000.gpu: DRM: failed to create ce channel, -22

A Google search suggests that I'm not the only one with this, but I
don't see it being discussed anywhere.

Is this known / expected?

This is with 4.6 and 4.7-rc4.  The firmware is installed.
