Title:
5.3.0-23-generic causes fans to spin when idle
Status in linux package in Ubuntu:
Fix Committed
Status in linux source package in Eoan:
In Progress
Status in linux source package in Focal:
Fix Committed
Bug description:
SRU Justification
Impact: "drm/i915/gen8+: Add RC6 CTX corruption WA" makes it
effectively impossible to enter RC6 for some Intel GPUs when a display
server is running. This results in increased energy usage and
temperature.
Fix: Upstream has changed too much to make the fixes there applicable,
but Chris Wilson has provided a patch for 5.3, here:
https://gitlab.freedesktop.org/drm/intel/issues/614#note_366057
Test Case: See test results below. On an affected machine powertop
will show increased RC6 usage on an idle desktop after the patch, and
other symptoms of excessive power use should also subside.
Regression Potential: The 5.3 patch is pretty straightforward, and
only adds running of an existing delayed worker to retire GPU
requests. No regressions have been reported in testing so far.

After upgrading to 5.3.0-23-generic the fans in my machine don't stop
running. They always sound like something is utilizing CPU - even with
no applications running after boot.
If I boot back to 5.3.0-19-generic it's fine.
My microcode version is reported as 0xd4 and iucode-tool reports:
iucode-tool: system has processor(s) with signature 0x000506e3
Let me know if you need anything else.
