Subject: 4.3 nouveau regression: nv04_fbcon_imageblit(?) deadlock
Date: Thu, 26 Nov 2015 19:10:28 +0200 (EET) [thread overview]
Message-ID: <alpine.LRH.2.20.1511261736160.8214@math.ut.ee> (raw)
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

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:

Is there anything else I can provide?
