I did try this kernel the other day and the system did lock up just like the one in the repository:
linux-image-3.11.0-7-generic_3.11.0-7.14~lp1227202v1_amd64.deb The system still locks up even with the latest kernel from the repository -- Linux lubuntu 3.11.0-7-generic #14-Ubuntu SMP Mon Sep 16 18:37:27 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux -- unless zram is turned off. After about 3 days of usage, I have yet to encounter a freeze after setting the following: sudo swapoff /dev/zram0 sudo swapoff /dev/zram1 sudo rmmod zram With zram on, the system will freeze sooner or later. Sometime it is within 15 minutes of cold boot. Other times, it will go for many hours. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1227202 Title: Unexpected freezes Saucy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1227202/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
