Hello,
As a preface, my config:
Dell Precision 7920 with two CPUs and the 1.4.1 BIOS.
Red Hat Fedora 28 with their v4.16.1 kernel.
I’m finding that the second CPU isn’t thermally managed. It seems to send about 1000 thermal distress interrupts/core/package/second under load and the second CPU throttles itself down to 1.7 GHz. If I force the fans to full speed via /sys, then the clock speed runs as expected (about 3.2 GHz).
Who is to blame here? Linux? Or the Dell BIOS? If the BIOS is to blame, how does one file bug reports against Dell?
Thanks,
Dave
