nouveau CALL_SUBR_ACTIVE errors using dma_bits=32 kernel on NV34

I tried your suggestion about setting dma_bits to 32 inside
drivers/gpu/drm/nouveau/core/subdev/vm/nv44.c.
but sadly the same issue arises (dmesg attached).
I hope I'm still wise to post those traces (from my NV34) in this bug report
and hope the root cause is common.
I currently use the drm kernel module with debug=2, debug=3 dumps too much
output, but let me know if this can provide additional useful info.
