OK, I'm pretty sure this is from gf119_disp_intr_error:

drm/nouveau/nvkm/engine/disp/gf119.c:
nv50_disp_chan_mthd(disp->chan[chid], NV_DBG_ERROR);

However what's odd is that preceding this line, there should have been a

        nvkm_error(subdev, "chid %d mthd %04x data %08x %08x %08x\n",
                   chid, (mthd & 0x0000ffc), data, mthd, unkn);

which isn't displayed. Furthermore, your logs appear to be missing
some fairly common prints. Did you mess with CONFIG_NOUVEAU_DEBUG*
symbols by any chance? Aha:

CONFIG_NOUVEAU_DEBUG=5
CONFIG_NOUVEAU_DEBUG_DEFAULT=2

You should adjust the default to 3 (info). And perhaps for the purpose
of this exercise, it might even be worth booting with
nouveau.debug=debug to hopefully get a bit more info about what's
going on.
