How can I provide a more detailed bug report? Please give 3.16-rc5 a shot. A considerable amount of rework has gone into 3.16 for DP support on nouveau. If you're still having issues, take a look at http://nouveau.freedesktop.org/wiki/Bugs/ for information on filing bugs. -ilia ^ permalink raw reply [flat|nested] 7+ messages in thread

Nope, sorry. You could try just copying over the drm directory, but it's unlikely to yield positive results. Just build a fresh kernel. -ilia ^ permalink raw reply [flat|nested] 7+ messages in thread

After installing and restarting: Exactly the same behaviour: dmesg complains about link error.... and about 10 secs later whole system crash :S So I power cycle the machine and everything works perfectly. Both connectors, notebook and dock. :) I could try to replicate the error if you are interested. Is there any plans to backport whatever fixed this issue to Long Term Support kernel tree? Thanks!

It might have been some sort of "warm" state left over from less-than-perfect drivers that will never happen again in practice. Or perhaps you accidentally booted the wrong kernel the first time around. > > Is there any plans to backport whatever fixed this issue to Long Term > Support kernel tree? Certainly not in mainline -- the changes were substantial, and only small fixes get backported in normal stable trees. Questions about what a distro might do should be brought up with that distro.
