upgrade to kernel 4.4.0-43 renders system unusable

[Gilles De Brouwer]

Hi,

After the update to kernel 4.4.0-43 laptop (asus zenbook UX305UA) became unsuable :
- touchpad not working
- usb mouse not working
- screen resultion not recognized anymore only allowing basic resolution
- I did not test sound, etc... since no pointing device was accepted anymore to navigate the gui
- Only possible interaction via dash/terminal

Problem is solved by switching back to kernel 4.4.0-42

Tell me what you need to diagnose the cause
Please give exact commands since I'm not a deep core techy.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1633679

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Hi,

apport did not work, since internet connection does not work.
See attached screenshot
Ponting device to select wifi connection is not working

Is there a way to collect this data off-line ?
And attach the file after to the bug after having switched back to kernel 4.4.0.42.

Thx

Hi,

just did the standard upgrade.
Saw kernel files 4.4.0-43 being downloaded (+ some other files)
Restarted on latest kernel

uname -a :
Linux UX305UA 4.4.0-43-generic #63-Ubuntu SMP Wed Oct 12 13:48:03 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

All works fine
So I suppose we can close the case

Thx
