I have an Aspire ES1-111 and facing the same issue. I use 14.04 LTS though with always the latest updates. I also tried to track the problem without success. I couldn't reproduce it on will. Nothing works when freeze occures, no crash dump, no logging, no SSH. Maybe it could be in connection with the Broadcom wifi card, because I had crash when it lost signal once... or twice, and lately it had a crash when wanted to disconnect wifi network to switch to cable. But I also tried using the laptop with wifi turned off for a while and I had crash during that time as well. I have no clue, but it is very annoying. If someone could remove the wifi card to test if it freeze again (that beast has proprietary drivers) but it can be done in a service point not to lose warranty, because the whole laptop must be opened... It seems like all the bay trail acers are affected.

I had the same issue with Ubuntu 15.04, but I thought that 15.10 might change it. I am running Ubuntu on an Acer Aspire ES1-311 (P1D5). I have no clue what causes this, my system just freezes and I can't do anything anymore. ctrl+alt+f1 doesn't work as well as alt+print+REISUB doesn't work either. It's just frozen. I have to power down manually. Last time I was programming only with a gnome-terminal and atom (editor) opened. I checked some log files but I couldn't find anything suspicious. Any ideas?
