System becomes unresponsive over 12 hour period

[Tom Beardsell]

Had to perform a hard reset to reboot, no SSH access, no response to pings. Nothing in syslog during freeze.

Does this happen when using the upper Linux kernel at <https://wiki.ubuntu.com/Kernel/MainlineBuilds>?

When answered please set this bug status back to "confirmed". Thank you.

[Tom Beardsell (tbeardsell)]

I'm not willing to install an upstream kernel just yet.

I will keep an eye on the system over the next 48 hours before trying
that, as apt-get update, remove and upgrade of some older kernels and
packages seems to have calmed the issue over the last 18 hours.

I'm still running 3.19.0-30-generic though for now.
