Since you are using hybrid graphics, you should probably use the bumblebee package if you aren't already. That provides controls over when the card is powered on, and powered off. In my case, I found that installing the proprietary Nvidia driver along with bumblebee solved my problems, while boosting battery life. You could try doing that, rather than blacklisting your discrete graphics card. Srikrishna Sekhar On 23 March 2015 at 00:05, Heiko Becker <heikobecker92@gmail.com> wrote:

I fixed all my nouveau problems, which were very seldom at that, by using the actual NVidia driver. Granted, it has a glitch or 2 from time to time and the GPU temps are a tad higher at idle. 3D performance though.... stellar!!

Hey everyone,

...

since the upgrade to kernel 3.19 I'm having some trouble with my

laptop:

...

When booting, it occasionally either crashes while establishing an

ibus connection or it floods the tty with some nouveau errors:

nouveau E[ PFIFO][0000:01:00.0] SCHED_ERROR [ UNK06 ]

Can someone help me fix this?

Thanks in advance,

Heiko

I was able to stop the scheduler errors from occuring by removing xf86-vide-nouveau and installing vesa. At least I'm able to see the other errors that come from nouveau

currently.

...

You can find them in a GitHub Gist: https://gist.github.com/HeikoBecker/be417e2d97a34636dfd4 This is the full dmesg output.

I hope someone can help me with this. Thanks in advance.

Regards,

Heiko

i might not be much help on this but here's some info.

---if it were me, i would update my bios/uefi.

---from your log output we see(lines 870 & 871):

"[ 9.863404] nouveau 0000:01:00.0: Direct firmware load for nouveau/nv117_fuc409c failed with error -2 [ 9.863409] nouveau 0000:01:00.0: Direct firmware load for nouveau/fuc409c failed with error -2 "

---so this might be useful:

---i would, of course be sure to double check everything on the arch nouveau wiki page

good luck

Hey everyone,

thanks for the help. After some searching I found out that the support for my graphics card was added into nouveau in this kernel version and therefore these problems did not occur before. As my laptop is a hybrid laptop and can either use Intel or Nvidia graphics, I fixed it by blacklisting nouveau.

Thanks to everyone for the help.
