Please attach dmesg output also

Created attachment 119703 [details]
output of /var/log/messages

I am sorry, I did not keep the output of dmesg, but I have saved the relevant part of the log file which might be indentical !?

Today after a reboot I found this in the output of dmesg:

[   30.428099] [drm:gen8_irq_handler] *ERROR* The master control interrupt lied (SDE)!

Not sure if that has got something to do with the bug ?

It's not relevant here.

output of dmesg

Today it happened again and I was able to save the output of dmesg.
Very often the whole computer freezes and I cannot do nothing anymore except restarting it.

Why? The fact that I ask questions or make relevant comments on a bug, which I by and large do more than most, does not mean that I would know *anything* about the actual bug behind the report. Here, I merely happened to know that comment #3 is another bug.

Hi ragadinks@gmail.com :

Can you provide the exact steps in order to reproduce this bug, in QA we have a Lenovo G50-80 with Intel(R) i5-5200U @2.2GHz and Intel HD Graphics 5500, i think that this hardware help us to reproduce this bug once we have the exact steps to reproduce it, as well did you do any extra configuration ?

Thanks

Sorry, I am just travelling and won't return till the end of this
month. I also replaced the buggy kernel with an older one because it
was impossible to work like this. Sometimes the problem arised when
starting X and sometimes when opening a some program that seemed to
put the graphic card under stress as it appeared to me.U will try to
reproduce the error when back at home, but right now I don't have the
laptop with me.

Regards
Arno
