Bumblebee/BBswitch error after upgrade to kernel 3.9.4

Hello community. The last full upgrade of June 4, in which the kernel was upgrade to v3.9.4 from v3.8.2, brought some complications for some kernel modules and as I'd like your keen eyes to help me shoot them all. Here they are:

- After the last kernel upgrade and bumblebee-git reinstallation, the bumblebee daemon could be systemctl-started although with the same configuration and access, it logs the following error

Could not set the GID of bumblebee

Any ideas why?

- BBswitch could not be systemctl-started anymore. Systemctl returns with the error

Unit bbswitch.service failed to load: No such file or directory.

although the kernel buffer says otherwise:

[   14.395884] bbswitch: version 0.7
[   14.395891] bbswitch: Found integrated VGA device 0000:00:02.0: \_SB_.PCI0.GFX0
[   14.395895] bbswitch: Found discrete VGA device 0000:01:00.0: \_SB_.PCI0.PEG0.PEGP
[   14.396042] bbswitch: detected an Optimus _DSM function
[   14.396078] bbswitch: disabling discrete graphics
[   14.441452] bbswitch: [b]Succesfully loaded[/b]. Discrete card 0000:01:00.0 is off
[  320.757595] bbswitch: enabling discrete graphics
[  321.246286] bbswitch: disabling discrete graphics

Where does this come from?

- Last but not least, the systemd-modules-load service could be not started.

I suspect these errors have something to do in common but miss some clues to start fixing them.
Could you give a hand? Thanks a lot.

bbswitch has no systemd unit. If bumblebeed fails to start, ensure that you have fully upgraded your system, including the filesystem package. bumblebeed should then be located at /usr/bin/bumblebeed.

What does journalctl say about bumblebeed?

Here's the output of a # journalctl -u bumblebeed -xmn 10

Is it possible that bumblebeed doesn't have access to the appropriate group causing all this?

Re: Bumblebee/BBswitch error after upgrade to kernel 3.9.4

No idea why you get EPERM. Does the bumblebee group exist? Besides that, I do not see issues, do you have any?

Re: Bumblebee/BBswitch error after upgrade to kernel 3.9.4

Me neither The bumblebee group exists ; the excerpt of the /etc/group indicates it.

users:x:100:
dbus:x:81:
avahi:x:84:
git:x:998:io
uuidd:x:68:
plugdev:x:46:io
polkitd:x:102:
bumblebee:x:997:io
ntp:x:87:
systemd-journal:x:190:

And I concur with you, besides the eperm, it seems there is no issue and bumblebeed causes no trouble -- which makes me want to pull my hair.

Could it be possible that the Intel pstate introduced in the kernel 3.9.x induces this error?
Since it's here, the cpu frequency scaling governor has been set by default to powersave instead of ondemand.

Re: Bumblebee/BBswitch error after upgrade to kernel 3.9.4

Does it work ok with the official bumblebee package? Did you reboot after switching to 3.9.4?

Re: Bumblebee/BBswitch error after upgrade to kernel 3.9.4

With either of bumblebee and bumblebee-git packages, the dameon hangs at the same step with the same error. The process was to upgrade to 3.9.4, right after the initramfs was generated, to recompile and reinstall bumblebee-git, terminated by a reboot. This was what is done at each full upgrade and insofar, no such problem. At first, the official bumblebee package was prefered over the one in aur. As it raises this error, the development version replaced it---without any luck.
