The server had been very stable for many years. I do not remember if the
crashes started happening after a particular update, but it only started
to happen recently, about a month before I upgraded to 14.04.2 LTS from
12.04 (I upgraded to 14.04.2 LTS because I thought it would stop the
occasional crashes, but the server crashes much more frequently after
the upgrade). I have a spare HD. If you could let me know how to install
old kernels, I can install them on the spare HD and test. I can start
testing by installing 12.04.1 LTS, but I don't know how to upgrade to
old kernels from there.

Also, since it's an old computer, do you think the crashes could be a
result of hardware failure? I tested both RAM and HD and they are both
fine. But I am wondering if other hardware failures could also cause
kernal panic. If so, are there ways to test?

Title:
  kernel panic, 14.04.2 LTS server crashes at random intervel

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  14.04.2 LTS server crashes in random interval, at least once every 24
  hours. Same error msg each time: "kernel panic - not syncing: Fatal
  exception in interrupt". I do not know what is triggering the crash -
  it seems that the crash can happen anytime at random. RAM passed
  memtest86 test without errors, and HD passed smartctl long test
  without errors. Also, the computer runs fine under Linux Mint 16 Petra
  using a bootable USB stick. Photo of screen after the crash is
  attached.
