Shaun Crampton, thank you for reporting this and helping make Ubuntu
better. Could you please provide the full computer model as noted on the
sticker of the computer itself (not from the Bug Description)?
** Description changed:
- Noticed my laptop getting hot over the last month or so. Investigating,
- I ran 'cpupower frequency-info' and found that all my cores were running
- at 2.8GHz pretty-much constantly despite being mostly idle.
+ Running 'cpupower frequency-info' shows all my cores running at 2.8GHz
+ constantly, despite being mostly idle. My laptop was using the
+ intel_pstate module for CPU frequency governing. I tried switching
+ between powersave and performance governors but they both showed the
+ same issue.

- I tried switching between powersave and performance governors but they
- both showed the same issue.
-
- Adding intel_pstate=disabled to my kernel command line switched over to
- using the acpi-cpufreq module and the ondemand governor. With that
- enabled, my CPU is back down to 800MHz-1.1GHz at idle, as expected and
- it immediately stopped overheating.
-
- Bug 1188647 covered disabling intel_pstate a while ago while it was
- considered buggy but now it's enabled again, it seems to be causing
- problems for me.
+ WORKAROUND: Add intel_pstate=disabled to my kernel command line.
