Yeah, I know. 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...
