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? -- Meelis Roos (mroos@linux.ee) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
