Bug#763272: bumblebee fails to disable discrete graphics card after upgrade to kernel 3.16

Package: bumblebee
Version: 3.2.1-5
Severity: important
Dear Maintainer,
I am running testing and Bumblebee was working properly to enable and disable
my Nvidia graphics chip when I was running kernel 3.14-X-amd64. Last night I
dist-upgraded and got kernel 3.16. This morning I noticed my laptop was
constantly running hot, so I investigated and discovered that the discrete
graphics was always on.
rlange at iset:~$ cat /proc/acpi/bbswitch
0000:01:00.0 ON
root at iset:~# cat /proc/acpi/bbswitch
0000:01:00.0 ON
root at iset:~# echo OFF > /proc/acpi/bbswitch
root at iset:~# cat /proc/acpi/bbswitch
0000:01:00.0 ON
Bumblebee still is able to load the nvidia kernel module and unload it.
However, it cannot actually turn off the discrete graphics chip.
# when no optirun processes are running:
rlange at iset:~$ lsmod | grep -i nvidia
# no output, therefore module not loaded
# fire up an optirun process and check again:
rlange at iset:~$ optirun glxgears&
rlange at iset:~$ lsmod | grep -i nvidia
nvidia 10490776 36
i2c_core 46012 8
drm,i915,i2c_i801,drm_kms_helper,i2c_algo_bit,nvidia,v4l2_common,videodev
# now, we terminate glxgears and check again:
lsmod | grep -i nvidia
# no output, therefore module has been unloaded
rlange at iset:~$ cat /proc/acpi/bbswitch
0000:01:00.0 ON
I see an error when I check the bumblebeed systemd status. I do not understand
how permission can be denied because bumblebeed runs as root:
