Description Stefano 2017-03-20 18:48:25 UTC 
As detailed here:
https://github.com/linrunner/TLP/issues/244

and here:
https://github.com/Bumblebee-Project/bbswitch/issues/140

kernel >3.6.8 added pcie_port_pm that is incompatible with bumblebee.

The workaround is to disable PCI Express power management at boot, passing pcie_port_pm=off, but that's hardly a solution.

Per upstream bug it seems a bbswitch bug
Comment 2 Stefano 2021-04-17 08:14:28 UTC 
Still true as of bumblebee 3.2.1_p20210112-r4
