H guys/gals
hope you can help me

I Have this bug
https://bugs.launchpad.net/ubuntu/+s...x/+bug/1488719

boot process ends with a frozen screen that says:

[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!
[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!
[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

can use control-alt-F1 etc
then login and startx but lost where to go from there

would it be possible to use a backport driver or something?

possibly useful code:-

also having issues with screen tearing which I think is related
also wifi but thats a realtek card so probably not related

Any help appreciated

Edit to add:
This is a brand new machine with brand new install
have not copied anything across what-so-ever

You seem to be able to log on to the system with a command line.

From there I would first try to do a

sudo apt-get update && sudo apt-get dist-upgrade

Then try to reboot.

Solved

Teunis
Thanks for your help
did try that but did not help

ended up trying 15.04 (kernel 3.19) which kinda worked
then from there I went to kernel.org and installed kernel 4.2, 4.25 and 4.3 (has a regression to this issue)
Kernel update was really daunting but turned out easy
kernel 4.25 solved this issue the other two still had the bug

so if you have this issue go to kernel.org get 4.25 kernel

you need 3 .deb files (linux image, linux headers.deb & headers-all.deb)

save them in a folder

move to the folder

then use:-

sudo dpkg -i *.deb

reboot into it

Wish I had done this spent ages trying to get drivers working but it was 30 minutes to do this for the first time
and a super cool learning experience to boot (bad pun intended)

Hope this helps someone

Update

Kernel 4.2.6 is even more stable, seems totally fixed now
