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=3Doff workaround.

There are more details for this bug from the reporter in IRC (search for
NanoSector):

In particular, Rick reported that the issue apparently also appears with ol=
der
kernels, including 4.3 to 4.8. This is significant and a surprising result
because kernel 4.8 plus pcie_port_pm=3Doff (or the d3cold_allowed change) s=
hould
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 s=
ure
to keep a dmesg around.
