See Bugzilla for the full thread. Goran: On Tuesday, I asked you to perform bisection. Any update on it? Anyway, I'm adding this regression to regzbot: #regzbot introduced: v6.4..v6.5-rc3 https://bugzilla.kernel.org/show_bug.cgi?id=217703 #regzbot title: significant temperature increase on XPS 17 9730 Thanks.
