I have the same bug with two computers, both running with zram. 3.8.0-27 works fine, but 3.8.0-29 freezes from time to time (especially on high RAM usage).
When doing "service zram-config stop", I see no further freezes. Also, I found a patch in linux upstream that could be related to this issue: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=94bcc7deb8fed472360ad72ef3717c5409057fca -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1215513 Title: System locks up, requires hard reset To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1215513/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
