--- Comment #8 from Peter Wu <pe...@lekensteyn.nl> ---
Pablo, the issues that bbswitch has is different from the one reported here.
bbswitch is not updated for 4.8 requiring the pcie_port_pm=off workaround.
There are more details for this bug from the reporter in IRC (search for
NanoSector):
https://people.freedesktop.org/~cbrill/dri-log/index.php?channel=nouveau&date=2016-10-22
In particular, Rick reported that the issue apparently also appears with older
kernels, including 4.3 to 4.8. This is significant and a surprising result
because kernel 4.8 plus pcie_port_pm=off (or the d3cold_allowed change) should
have the same result as 4.7 or before. Rick, can you re-test it with 4.7?
It also occurs to me that older kernels might not support your GPU, so be sure
to keep a dmesg around.
