Title:
  Clock issues on AMD Opteron(tm) Processor 6320

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  In doing certification testing on an HP DL385p Gen8 server with an AMD
  Opteron(tm) Processor 6320 CPU, we've run into some clock issues, as
  illustrated by the following:

  $ for x in `seq 0 9`; do start=`date +"%s"`; sleep 60; stop=`date +"%s"`; echo "$stop - $start"|bc; done
  65
  62
  60
  60
  60
  61
  60
  60
  60
  61

  This should produce a string of "60" values, and does on most systems;
  however, on the DL385p Gen8, the output shown above is quite
  irregular. (The test we use in the certification suite is more
  specialized and is not this exact test; the above is simply an easy-
  to-reproduce bash variant.)

  The system in question is "phelps" in OIL.
