Gonmator, could you please test the latest upstream kernel available from the
very top line at the top of the page (not the daily folder) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine the issue. Once you've tested the upstream
kernel, please comment on which kernel version specifically you tested. If this
bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested exactly
shown as:
kernel-fixed-upstream-3.17-rc3
This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
[Acer AO 751h] Laptop requires a hard reset to recover from suspend
state
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Since update to Lubuntu 14.04.1 from lubuntu 13.10, the laptop is not
able to resume from suspend anymore. I've checked this happens runing
lubuntu 14.04.01 LiveCD too (but not with the LiveCD of previous
version of Lubuntu). If I start the OS with the previous kernel
3.11.0-26 I have not the problem. But starting with kernel 3.13.0-32
or 3.13.0-34 it is there.
If I suspend the laptop closing the lid, or from the menu, pressing
the power button (to show the exit menu) or running sudo pm-suspend,
the laptop get suspended, the screen will off, and the power button
led blinks as expected. But then it is not possible to awake again
neither pressing a key or pressing the power button. If in that state
I try to power off keeping pressed the power button, that still does
not work: the blink led still blinks and nothing happens. The only way
to recover the system is removing the battery and turning on again.
That I expect:
After suspend the laptop, I am able to resume it again, just pressing a key,
or pressing the power button.
I've tried starting with "acpi_osi=linux" but didn't help. (anyway,
that was not necessary with the previous kernel/OS version).
