--- Comment #36 from vdanjean at free.fr <vdanjean.ml at free.fr> ---
I suffer from the same bug on HP ZBook. However, with the last Debian kernel
(ie plain 4.3), I still got an 'error -22' and no "pmu: hw bug workaround
enabled" log:

$ dmesg | grep nouveau

I will put in attachment the result of acpidump on my machine.
