--- Comment #6 from Peter Wu <peter at lekensteyn.nl> ---
The problem is that nouveau_switcheroo_optimus_dsm() unconditionally calls
function 0x1B ("NOUVEAU_DSM_OPTIMUS_FLAGS") without checking that this function
is actually supported. Lenovo's firmware decides to run into an infinite loop
in this case instead of returning an error code.
Proposed patch:
