I just upgraded my hypervisor to Ubuntu 14.04 in an attempt to resolve this issue as Simon experienced. However under heavy I/O of 'aptitude upgrade', I've had 3 more occurences of this with hours of upgrading the host to 14.04. So it appears not to be related to the hypervisor.
This leads me down the path that most of the affected systems have been upgraded from 10.04 -> 12.04 -> 14.04. Which would point to something in the upgrade path affecting this. As Simon re-installed all of his systems and didn't have the issue anymore. I could try random kernels on machines, but some information from a kernel developer on how to debug this would be very useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1298972 Title: stacktrace in ext4: /build/buildd/linux-3.13.0/fs/ext4/ext4_jbd2.c:259 __ext4_handle_dirty_metadata+0x1a2/0x1c0() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1298972/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
