Like Hans, I'm seeing this on 12.04 LTS. linux-image-3.2.0-53-generic- pae seems to enable zram by default, which results in lots of "scheduling while atomic" errors in syslog and occasional lockups (machine still responds to ping, but not ssh, desktop frozen.)
This seems like a pretty critical problem now that it's affecting current LTS.. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- 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 (possibly causing complete machine lockup) 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
