Issues with vgaswitcheroo disappearing?

[Rakot]

This bug is still present in 3.12.3 and 3.13-rc2 in opensuse. Is there any news related to the bug?

If you're running Arch Linux, it seems like the linux-git AUR package builds successfully: https://aur.archlinux.org/packages/linux-git/

And I've had no crashes, and vgaswitcheroo/switch remains and reports dynamic power in my discrete GPU.

I was digging around the kernel.org bugzilla and I came across this bug which may be what we're running into: https://bugzilla.kernel.org/show_bug.cgi?id=61891

kernel 3.13: freeze 10sec after boot( if run something with discrete card, do not freeze)
like

DRI_PRIME=1 glxgears

Of course that defeats the purpose of runtime power management, since the reason that it doesn't crash on 3.13 when you're running glxgears on the discrete card is because it's not actually turning off.

Do you have dpm enabled?

Does it work with dpm disabled?

I've never done so before, and am not terrible familiar with the process. I did, however, do a little poking and prodding of my own and I found:
1. It seems to be an issue with xf86-video-ati/intel, which I had assumed

The ddxes are not really aware of or involved in hybrid graphics. They just send commands to the kernel driver to draw stuff. The problem is mostly likely kernel related.

I also noticed these errors printed to stdout (before starting X) when testing on linux-next (with stable intel/ati drivers):

error waiting for ring[6] to become idle

*ERROR* radeon: failed testing IB on ring 5

I'm working on getting some more definitive error logs, my Linux partition is not the most stable right now.
