[Bug 1563970] [NEW] Clock issues on AMD Opteron(tm) Processor 6320

 

Public bug reported:

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.
