I've looked at the atop logs since the machine got rebooted.
The CPU usage actually increases during the first 24 hours
to reach about 100%:
  00:30  1%
  00:40  2%
  01:00  3%
  01:10  4%
  01:20  5%
  02:00  6%
  03:00  8%
  04:00 11%
  05:00  9%
  06:00 11%
  07:00 12%
  08:00 14%
  09:00 10%
  10:00 10%
  11:00 12%
  12:00 16%
  13:00 17%
  14:00 18%
  15:00 20%
  16:00 21%
  17:00 24%
  18:00 29%
  19:00 38%
  20:00 42%
  21:00 49%
  21:30 59%
  22:00 68%
  22:30 86%
  23:00 93%
  24:00 96%

So bug 922630 looks like the same bug as bug 993051.
