The problem is that I cannot unload the driver, because modprobe always complains about it being in use. However, I found that with 4.17-wip the system actually remains stable after disabling the hardware, as long as I don't try to use it - which was not the case before, where it would crash much faster. But seriously, what I'm doing is that I have two boot entries, one that blacklists amdgpu and does the acpi_call thingy and one that doesn't. So one for mobile usage, one for gaming. Would be nice, though, if I did not need to reboot to switch between the two use cases...</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
