[2] Here are the exact steps I took for various stress-testing (with
    root privileges when necessary, such as for memtester):

  aptitude install stress
  stress --cpu 8 --io 4 --vm 2 --timeout 10s --dry-run
  stress --cpu 8 --io 4 --vm 2 --hdd 3 --timeout 60s
  stress --cpu 8 --io 8 --vm 8 --hdd 4 --timeout 5m

  aptitude install stressapptest
  stressapptest -m 8 -i 4 -C 4 -W -s 30
  stressapptest -m 8 -i 4 -C 4 -W -f /root/sat-file-test --filesize 1gb -s 30
  stressapptest -m 8 -i 4 -C 4 -W -f /root/sat-file-test --filesize 1024 --random-threads 4 -s 30
  stressapptest -m 8 -i 4 -C 4 -W --cc_test -s 30
  stressapptest -m 8 -i 4 -C 4 -W --local_numa -s 30
  stressapptest -m 8 -i 4 -C 4 -W -n 127.0.0.1 --listen -s 30
  stressapptest -m 12 -i 6 -C 8 -W -f /root/sat-file-test --filesize 1024 --random-threads 4 -n 127.0.0
+.1 --listen -s 300

  aptitude install linux-source
  cp /usr/src/linux-source-3.2.tar.bz2 /root/
  tar xvfj linux-source-3.2.tar.bz2
  cd linux-source-3.2/
  make defconfig
  time make 1>LOG 2>ERR
  make mrproper
  make defconfig
  time make -j16 1>LOG 2>ERR

  aptitude install memtester
  memtester 30G

  aptitude install memtest86+  # reboot and run for 3+ days
