After some days with the updated 3.8 kernel I never see this issue anymore.
Upstream 3.2.52 reverted a patch already reverted on 3.2.0-54: https://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.52 I'll close this if no one experience other problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1217189 Title: Buffer I/O error on device zram0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1217189/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
