Gnome freezes on Debian 8, "intel_dp_start_link_train: too many full retries, give up"
 

Sometimes, while I'm using Debian 8 on my macbook air 13" from 2011 with Debian 8, it freezes. I can move the mouse but it's laggy, and I can switch to other terminals. Even the clock freezes. When this error occurs, and I switch to another terminal by pressing Control Alt F1 for example, I can see this in the login screen:

I think it's related to the intel graphics card, but I don't know what to do. Sometimes if I wait for like, 1 minute, the gnome starts working again, sometimes I have to restart.

I've searched about this on the internet but I couldn't find a fix, and I've not found this particular error, just boot errors with this phrase. Does somebody know what's happening? Today it occured like 5 times while I was watching videos, then the browser closed the tab the video was running and it worked again, but sometimes it occur even if the browser isn't open.

Does this has something to do with intel drivers?

Screenshot looks like hardware failure. So, maybe blow the unit out with air to clean out dust bunnies maybe.

Maybe also do memtest (grub screen should have it) to test ram over night.

Then maybe have to think of running a smartctl test on hard drive <last resort stuff> to see if the hard drive is failing.

Software solution. Try installing another Desktop Environment like XFCE and see if it freezes also.
