I can confirm, or at least is no longer freezing after several ours of work under the 4.3.0 rc6 mainline kernel. If this changes and hangs again I will post a re-tag the issue. This is the only kernel I tried yesterday, as rc7 hasn't been compiled for amd64 yet.
If you want I can try kernels from the bottom up , to see in what exactly version is fixed. Thanks. ** Tags added: kernel-bug-exists-upstream kernel-fixed-upstream-4.3-rc6 ** Tags removed: kernel-bug-exists-upstream ** Tags added: kernel-fixed-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- 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/1509871 Title: Ubuntu Freezes occasionally Status in linux package in Ubuntu: Confirmed Bug description: I have the same laptop model and this is the same problem as bug #1509723. Acer ES1-311 latest 1.11 bios, Ubuntu Gnome 15.10. The system literally freezes for no reason, is completely random, I can't reproduce it twice doing the same thing, sometimes it hangs only using firefox, other times with nautilus only open etc. Let me know if you need me to post some more logs, and I'm I apologize for pasting nonsense in the other bug, as I didn't know i have to duplicate the issue to attach new logs.
