New kernel update cause seriouse video problems.

[Várkuli Miklós Gábor]

Test machine:

Asus Eee PC 1000H
CPU: Intel Atom N270 1,6 GHz
Video: Intel GMA950

no proprietary drivers in use

Last stable kernel without the error: 4.4.0-112
System: current Xubuntu 16.04 LTS previously Lubuntu 16.4 LTS

After this kernel was updated 4/5 of the desktop disappear or filled with random pixels and only a small portion is rendered normally. This problem is not occuring when switching back to the older kerrnel mentioned above. I tried this with fresh install and with old install upgraded. Results were the same. I can't provide data from the faulty state since I can't see enough from the desktop to send or even start a report. The current bug report is from the properly working, stable system .

Lubuntu, debian and xubuntu is making the same error after kernel update. We have 2 stronger notebook an asus and a fujitsu siemens business class. They both using proprietary drivers: Nvidia and Intel microcode and the error doesn't occured there. I didn't tried to switch back to free drivers. They both use lubuntu 16.04 LTS with newest kernel and drivers.

Thanks for your help and the great operating system you all created. Sincerely. Miklós Várkuli.
