Perhaps a clue: after the upgrade, I was also finding my wifi was a
little flaky. Last week I disabled wifi and unloaded the ath5k drivers
and other related drivers. The system has been up 10 days now, which is
the longest uptime since this problem started.

>From dmesg:

ath5k: phy0: Atheros AR2414 chip found (MAC: 0x79, PHY: 0x45)

Could this be the culprit?

Title:
  System hangs randomly

Status in linux-lts-trusty package in Ubuntu:
  Confirmed

Bug description:
  I recently upgraded from 12.04 to 14.04. Afterwards, my system started
  hanging randomly, sometimes after just a couple hours of use, and the
  longest it went was about 32 hours. It's a full on freeze, not just X:
  Ctrl+Alt+Fx does nothing. SysRq+REISUB does nothing. I've tried
  tailing syslog and watching dmesg and there is nothing interesting
  logged near the hang.

  I ran memtest86+ two full passes, no errors.

  Assuming maybe there was a problem with the installation or upgrade
  process, I tried booting from a 14.04.1 USB (tried both 32-bit and
  64-bit), and both hang after a few hours. I also tried stepping back,
  using a 12.10 USB that I found and it also hangs.

  Assuming it was related to newer kernel, I then tried to boot from a
  brand new 12.04.5 USB (using the latest 3.13.0-32-generic kernel), and
  the system did *NOT* hang... I ran it  for five full days with no
  problems before I rebooted to continue troubleshooting the problem --
  so the newest 12.04 still seems good and the latest kernel seems good.
  But something in 12.10 and beyond is bad.

  I installed a crash-dump kernel and it doesn't seem to work - still
  hangs and doesn't load the kernel.

  I attempted to find help in the ubuntu forums, without much luck:
