Subject4.3 nouveau regression: nv04_fbcon_imageblit(?) deadlock
Hello, this is a report about a PC with 3 nvidia cards - PCI-E NV44, AGP 
NV34 and PCI NV05. Only NV44 has monitor attached currently.

4.2.0 (both packaged and self-compiled) worked fine, 4.3.0 and 4.4-rc2
exhibit a problem: after the system has started up, I start getting
messages like INFO: task kworker/0:2:652 blocked for more than 120
seconds. where nv04_fbcon_imageblit and nouveau_pmops_runtime_suspend
show up in trace. The trace keeps reappearing, also breaking lspci and
clean reboot (they hang).

dmesg from 4.4-rc2, drm-debug=0xe
http://kodu.ut.ee/~mroos/download/dm-nouveau-4.4-rc2

dmesg from 4.2.0, drm.debug=0xe
http://kodu.ut.ee/~mroos/download/dm-nouveau-4.2

lspci -vvv
http://kodu.ut.ee/~mroos/download/lspci.nouveau

config:
http://kodu.ut.ee/~mroos/download/nouveau-config

Is there anything else I can provide?
