Description qzerty 2016-01-06 18:03:37 UTC 
On my very old laptop, that is equipped with an Ati Mobility Radeon
X700, sometimes (and, sadly, I have to use this word, because I found no
regularity pattern for the occurrence of this bug) randomly the desktop
session locks, that is I can only move the mouse pointer, but I cannot
interact anymore with the desktop session. I am forced to login trough
ssh from another pc and to restart the laptop.

In Xorg.0.log I found these lines that are, in my opinion, related to
the crash:

(EE) [mi] EQ overflowing.  Additional events will be discarded until existing events are processed.

drm/radeon: Always use indirect access for CRTC(2)_GEN_CNTL registers

Does this kernel patch help by any chance?
Comment 2 Ernst Sjöstrand 2016-01-07 15:45:31 UTC 
Since powerplay I'm getting something with this backtrace on AMDGPU also, in bug 92996

Not related. The event queue (EQ) overflowing is a generic symptom which can be triggered by many different causes.

However, I tried the same to build the kernel packages, and I installed them, but then my desktop is screwed as you can see in this picture:

Comment 5 qzerty 2016-01-08 13:09:19 UTC 
In the meanwhile, I moved to xenial (development release) Lubuntu, that uses kernel 4.3.x, I'll let you know if there are improvements.
Comment 6 qzerty 2016-01-09 11:33:29 UTC 
Yesterday, after upgrading to Xenial, I had an entire day without the problem, but today immediately after booting my notebook, the desktop freezed and I couldn't even move the mouse pointer. I could however login trough ssh, and I got the same errors in dmesg/syslog:

Please attach the actual patch you ended up using for the build.
Comment 8 qzerty 2016-01-18 10:46:24 UTC 
Could you explain me how to to identify what you refer to the "actual patch"? I am not so accustomed to kernel patching, I just followed this guidelines https://www.kernel.org/doc/Documentation/applying-patches.txt
with Ubuntu kernel sources 4.2.0
I will retry however using 4.3.0 sources as soon as possible.

> Could you explain me how to to identify what you refer to the "actual

The actual changes you ended up building the kernel with. E.g. make a copy of the kernel tree before applying the patch, then after applying the patch create a diff using

 diff -ru <copy of kernel tree> <kernel tree> >actual-changes.diff
Comment 10 qzerty 2016-01-23 10:35:44 UTC 
Created attachment 121230 [details]
File describing changes to kernel tree
Comment 11 qzerty 2016-01-23 10:37:03 UTC 
Ok, I have tried to apply the patch to Ubuntu kernel tree 4.3.0, but the error I get is the same as above. I attach the actual-changes.diff
