UPDATE: So I tracked down the issue. It seems the nvidia card powers up right before suspend. This is expected bbswitch behaviour:

[ 4195.214014] bbswitch: enabling discrete graphics

But for some reason the card is not powered down during the suspend time so as a result it drains battery.

The problem occurs even if I remove the bbswitch module and disable bumblebee.

ideas?

I got a new machine that drains disproportionate amount of battery during sleep: ~12%/hour. It's not a battery problem as the system makes it nearly 5 hours on normal use. Something is definitely wrong. Also the machine gets quite warm while its sleeping (Warmer than when it's running!), leading me to believe that the CPUs fail to suspend or that the nvidia GPU gets turned on prior to sleep? I can't find anything suspicious on dmesg:

Any ideas? Running on Arch Linux, Intel i7 4720 HQ and GTX 970M

  • The clue is at the the top, I think, about i915. You have a discrete/intel GPU hybrid? Sorry, you already mention it in the question. Yes, that's probably it. – mikeserv Jul 5 '15 at 8:49
  • Could you elaborate? It is the integrated GPU that has some sort of crash, I don't see any signs of the discrete there? – XapaJIaMnu Jul 5 '15 at 8:52
  • That's because they don't both run at the same time. The way they're supposed to work is one powers on while the other powers off. Your integrated GPU is probably called up by the kms drm drivers only to find the nvidia (which uses its own special kms thingy) is already at full-throttle - only to throw your exception. I'm pretty sure there are ways around it. – mikeserv Jul 5 '15 at 8:58
  • I just checked. The nvidia is powered down at suspend. (via the proc interface) it can't be interfering. Also the intel is always powered on because it's the only one connected to the display output (X). Nvidia draws on it via virtualGL. – XapaJIaMnu Jul 5 '15 at 9:26
  • Well, in that linked comment thread the op eventually says that the nvidia was being powered up when the intel powered down at suspend. It's just a quick one I found at the time. Anyway, I could be wrong about why, but your error definitely points to your GPU – mikeserv Jul 5 '15 at 9:28
