@ Joseph Salisbury: As expected due to the results during Kernel install, the machine booted OK but without Wifi. So, it is not possible for me at this time to perform any further tests with 4.7.0-040700rc1-generic.
Now I'm back to the old 4.4.0-24, and just applied the following workaround: ================================== 1. sudo nano /etc/default/grub 2. There is a line in that: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" (like this), replace with: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1" Save it (CTRL+O) 3. sudo update-grub 4. sudo reboot ================================== I'll be back with the results in a couple of day, or maybe sooner if it freezes again. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1593226 Title: [Acer Aspire ES1-411] Ubuntu freezes occasionally Status in linux package in Ubuntu: Incomplete Bug description: I am running Ubuntu 16.04 and my notebook freezes occasionally. I am running Ubuntu on an Acer Aspire ES1-411 (P6B1). There's also an identical Bug filled with Acer Aspire ES1-311 and both Ubuntu 15.04 & 15.10 by Christian Wansart here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509723 I have no clue what causes this, my system just freezes and I can't do anything anymore. When it happens, I have tried the following secuence without any luck, I have to power down manually: 1. ALT + F2, type xkill + ENTER. 2. Press Alt+Ctrl+F1. 3. While holding Alt and the SysReq (Print Screen) keys, type REISUB. Last time I was only viewing a Youtube video using Firefox. I checked some log files but I couldn't find anything suspicious. Any ideas?
