This problem can be reproduced 100% of the time on my machine. It doesn’t matter if re/started, suspend/resume, clean shutdown, …
I can also reproduce it with the card in a “warm” state:
tee /proc/acpi/bbswitch <<< ON
After the first failed attempt however I can’t turn the card back on. It completely ignores acpi calls.
The other problem I have is the rather restrictive bios. I can’t activate/deactivate or choose optimus from the bios.
The card woks fine with kernel 3.9.9 and nvidia 319.32
