--- Comment #5 from Alex Deucher <agd5f at yahoo.com> --- (In reply to comment #4) > I'm not sure if this has anything to do with this bug, but the PCI config > space is all messed up when running on the integrated GPU: When you disable the GPU the hardware is physically powered off so you are accessing non-existent registers. You need to power up the GPU using vgaswitcheroo before loading/resuming the driver or access the config space with lspci. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
