Sorry to not have any good news.

I just upgraded to rsyslog (proposed).

From /var/log/apt/term.log:
    Setting up rsyslog (4.2.0-2ubuntu5.1) ...
    rsyslog start/running, process 26509

The problem still exists. i.e. when load goes up, CPU gets hot and rsyslog starts spewing at a high rate, alternating between high temp and normal temp which makes the CPU-util problem even worse.

Brief excerpt from the log:
Nov 6 11:21:28 ze kernel: [497797.855109] CPU1: Temperature above threshold, cpu clock throttled (total events = 18517766)
Nov 6 11:21:28 ze kernel: [497797.856109] CPU5: Temperature/speed normal
Nov 6 11:21:28 ze kernel: [497797.856112] CPU1: Temperature/speed normal
...
Rate of printing under load is 2400 lines/second (this is a 8-core machine)
    $ grep '^Nov 6 11:21:28' /var/log/syslog | wc -l
   2400

The only difference I see is this regression in my logs:

Nov 6 09:06:59 ze kernel: imklog 4.2.0, log source = /var/run/rsyslog/kmsg started.
Nov 6 09:06:59 ze rsyslogd: rsyslogd's groupid changed to 102
Nov 6 09:06:59 ze rsyslogd: rsyslogd's userid changed to 101
Nov 6 09:06:59 ze rsyslogd-2039: Could no open output file '/dev/xconsole' [try http://www.rsyslog.com/e/2039 ]

(never seen the /dev/xconsole error before)
My system has no /dev/xconsole

Will gladly provide more data, just ask.
Thanks.
