[Bug 1594046] Re: lts 16.04 crashes frequently on acer TC-605

[David Johnston]

Seems similar to 
https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1574951
(found as first case with search for Acer alone, without mentioning distro, or the words crashes, frequently, or the machine model. 

I wasnt sure which package needed to be noted so picked the ubuntu-release package. 
maybe should have indicated unity or compiz or something like that. 

Also did searches using Acer + freeeze, 
for LTS 16.04 release -

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1578944
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1528880
similar for other releases - 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1511844
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509723
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509723
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/733392


and search for acer + crash 
but the only one found which seemed relevant was the first one listed above - 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1592442


Based on this suggestion, I have added a line to the grub entry for my dual boot start menu - 
http://askubuntu.com/questions/776069/ubuntu-16-04-freezes-during-use
(thanks to the reporter of bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1578944 for the reference)

Will keep an eye on the system and advise if the above workaround avoids the problem. 
If it does, it may suggest how the underlying cause can be found and fixed so the need for the workaround can be obviated.

Title:
  lts 16.04 crashes frequently on acer TC-605

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  I recently installed ubuntu 16.04 LTS release when I did an upgrade to
  whingedoze 10 (to get the product key then clean install, to set up a
  dual boot with a linux distro).

  It works reasonably, but crashes often after being left to go into sleep mode. 
  I tried changing the sleep/hibernate options to avoid letting it go to sleep, and that decreased the frequency with which I hit crashes under those circumstances, but has highlighted that it still crashes at other unexpected times. 

  I have noticed it crash when running browser games and also when
  playing audio and when trying to install apps, but it is intermittent.
  I go back to the same set of apps and they operate OK and I cant
  reproduce the problem. When the machine locks I do a hard shutdown by
  holding down the power key, and then when ubuntu starts up again
  usually there are bug report dialogue boxes which pop up.

  I also get those dialgue boxes sometimes even after having just done normal shutdowns. 
  I have clicked send report on almost all of them, and it has prompted me for the root password and seems to have sent bug reports. 

  I want to contribute to find the problems and make the release better,
  but the crashes are happening so frequently it makes me wonder whether
  the release is just too unstable to use, or just not compatible with
  this hardware. Windows 10 has never crashed on this machine. Its a
  family machine, so my wife often uses the windows 10 install, and she
  hasnt had any problems with it.
